  • HCF of 45 and 27 - 45 = 27 x 1 + 18 27 = 18 x 1 + 9 18 = 9 x 2 + 0 So, HCF (45, 27) = 9 d = 9 = 27x + 45y Make a linear combination- 9=27-18×1 =27-(45-27×1)×1 (18=45-27×1) =27-45×1+27×1 =2×27-1×45 =27x+45y (x=2,y=-1)

    according to question,

                 4x + 2y = 132

         ==>  2x + y = 66 ----------------------------------------------(1)

    and,       x + y = 39   ----------------------------------------------(2)

     

    solving (1) & (2)

    we get; x = 27 and y = 12

***** This article is about penises of animals in general. For the human organ, see human *****. For the male reproductive system, see Male reproductive system. "*****" and "Penile" redirect here. For the magnetic resonance imaging technique, see Proton-enhanced nuclear induction spectroscopy. For the community in Kentucky, see Penile, Louisville. ***** of an Asian elephant A ***** (plural penises or penes /-niːz/) is the primary sexual organ that male animals use to inseminate sexually receptive mates (usually females and hermaphrodites respectively) during copulation.[1] Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a ***** in every animal species, and in those species in which the male does bear a so-called *****, the penes in the various species are not necessarily homologous. For example, the ***** of a mammal is at most analogous to the ***** of a male insect or barnacle.[citation needed] The term ***** applies to many intromittent organs, but not to all; for example the intromittent organ of most cephalopoda is the hectocotylus, a specialised arm, and male spiders use their pedipalps. Even within the Vertebrata there are morphological variants with specific terminology, such as hemipenes. In most species of animals in which there is an organ that might reasonably be described as a *****, it has no major function other than intromission, or at least conveying the sperm to the female, but in the placental mammals the ***** bears the distal part of the urethra, which discharges both urine during urination and semen during copulation.[2] In different animals See also: Category:Animal penises. Vertebrates Birds See also: Intromittent organ § Birds, and Bird anatomy § Urogenital and Endocrine systems Mallard pseudo-*****[dubious ] Most male birds (e.g., roosters and turkeys) have a cloaca (also present on the female), but not a *****. Among bird species with a ***** are paleognathes (tinamous and ratites)[3] and Anatidae (ducks, geese and swans).[4] A bird ***** is different in structure from mammal penises, being an erectile expansion of the cloacal wall and being erected by lymph, not blood.[5] It is usually partially feathered and in some species features spines and brush-like filaments, and in flaccid state curls up inside the cloaca. The lake duck (also called Argentine blue-bill) has the largest ***** in relation to body size of all vertebrates; while usually about half the body size (20 cm), a specimen with a ***** 42.5 cm long is documented. While most male birds have no external genitalia, male waterfowl (Anatidae) have a phallus. Most birds mate with the males balancing on top of the females and touching cloacas in a "cloacal kiss"; this makes forceful insemination very difficult. The phallus that male waterfowl have evolved everts out of their bodies (in a clockwise coil) and aids in inseminating females without their cooperation.[6] The male waterfowl evolution of a phallus to forcefully copulate with females has led to counteradaptations in females in the form of vaginal structures called dead end sacs and clockwise coils. These structures make it harder for males to achieve intromission. The clockwise coils are significant because the male phallus everts out of their body in a counter-clockwise spiral; therefore, a clockwise vaginal structure would impede forceful copulation. Studies have shown that the longer a male's phallus is, the more elaborate the vaginal structures were.[6] The lake duck is notable for possessing, in relation to body length, the longest ***** of all vertebrates; the *****, which is typically coiled up in flaccid state, can reach about the same length as the animal himself when fully erect, but is more commonly about half the bird's length.[7][8] It is theorized that the remarkable size of their spiny penises with bristled tips may have evolved in response to competitive pressure in these highly promiscuous birds, removing sperm from previous matings in the manner of a bottle brush. Male and female emus are similar in appearance,[9] although the male's ***** can become visible when it defecates.[10] The male tinamou has a corkscrew shaped *****, similar to those of the ratites and to the hemipenis of some reptiles. Females have a small phallic organ in the cloaca which becomes larger during the breeding season.[11] Mammals Wikimedia Commons has media related to Mammal *****. External male genitalia of a Labrador Retriever. As with any other bodily attribute, the length and girth of the ***** can be highly variable between mammals of different species.[12][13] In many mammals, the size of a flaccid ***** is smaller than its erect size. In the realm of absolute size, the smallest vertebrate ***** belongs to the common shrew (5 mm or 0.2 inches).[citation needed] A bone called the baculum or os ***** is present in most mammals but absent in humans, cattle and horses. In mammals the ***** is divided into three parts:[14] Roots (crura): these begin at the caudal border of the pelvic ischial arch. Body: the part of the ***** extending from the roots. Glans: the free end of the *****. The internal structures of the ***** consist mainly of cavernous, erectile tissue, which is a collection of blood sinusoids separated by sheets of connective tissue (trabeculae). Some mammals have a lot of erectile tissue relative to connective tissue, for example horses. Because of this a horse's ***** can enlarge more than a bull's *****. The urethra is on the ventral side of the body of the *****. As a general rule, a mammal's ***** is proportional to its body size, but this varies greatly between species – even between closely related ones. For example, an adult gorilla's erect ***** is about 4 cm (1.5 in) in length; an adult chimpanzee, significantly smaller (in body size) than a gorilla, has a ***** size about double that of the gorilla. In comparison, the human ***** is larger than that of any other primate, both in proportion to body size and in absolute terms.[15] Even-toed ungulates (Artiodactyla) The penises of even-toed ungulates are curved in an S-shape when not erect.[16] In bulls, rams and boars, the sigmoid flexure of the ***** straightens out during erection.[17] When mating, the tip of a male pronghorn's ***** is often the first part to touch the female pronghorn.[18] The pronghorn's ***** is about 5 inches (13 cm) long, and is shaped like an ice pick.[19] The front of a pronghorn's glans ***** is relatively flat, while the back is relatively thick.[20] The male pronghorn usually ejaculates immediately after intromission.[21][22] The ***** of a dromedary camel is covered by a triangular penile sheath opening backwards,[23] and is about 60 cm (24 in) long.[24][25] The camelmen often aid the male to enter his ***** into the female's vulva, though the male is considered able to do it on his own. Copulation time ranges from 7 to 35 minutes, averaging 11–15 minutes.[26][27] Wikimedia Commons has media related to Bull *****. Bulls have a fibro-elastic *****. Given the small amount of erectile tissue, there is little enlargement after erection. The ***** is quite rigid when non-erect, and becomes even more rigid during erection. Protrusion is not affected much by erection, but more by relaxation of the retractor ***** muscle and straightening of the sigmoid flexure.[28][14][29] The male genitalia of mouse deer are similar to those of pigs.[30] A boar's *****, which rotates rhythmically during copulation,[31] is about 18 inches (46 cm) long, and ejaculates about a pint of semen.[32] Wild boars have a roughly egg-sized sack near the opening of the *****, which collects urine and emits a sharp odour. The purpose of this is not fully understood.[33] Deer Main article: Deer ***** A stag's ***** forms an S-shaped curve when it is not erect, and is retracted into its sheath by the retractor ***** muscle.[34] Some deer species spray urine on their bodies by urinating from an erect *****.[35] One type of scent-marking behavior in elk is known as "thrash-urination,[36][37] which typically involves palpitation of the erect *****.[37][38][39] A male elk's urethra points upward so that urine is sprayed almost at a right angle to the *****.[37] A sambar stag will mark himself by spraying urine directly in the face with a highly mobile *****, which is often erect during its rutting activities.[40] Red deer stags often have erect penises during combat.[41] Cetaceans Penises of minke whales on display at the Icelandic Phallological Museum Wikimedia Commons has media related to Cetacea *****. Cetaceans have fibroelastic penises, similar to those of Artiodactyla.[42] The tip of the cetacean *****, which tapers toward the end, is called the pars intrapraeputialis or terminal cone.[43] The blue whale has the largest ***** of any organism on the planet, typically measuring 8–10 feet (2.4–3.0 m).[44] Accurate measurements of the blue whale are difficult to take because the whale's erect length can only be observed during mating.[45] The ***** on a right whale can be up to 2.7 m (8.9 ft) – the testes, at up to 2 m (6.6 ft) in length, 78 cm (2.56 ft) in diameter, and weighing up to 525 lb (238 kg), are also by far the largest of any animal on Earth.[46] Dolphins' reproductive organs are located on the underside of the body. Male dolphins have two slits, one concealing the ***** and one further behind for the ****.[47][48][49][50] On at least one occasion, a dolphin was known to tow bathers through the water by hooking his large ***** around them.[51] Between male bottlenose dolphins, homosexual behaviour includes rubbing of genitals against each other, which sometimes leads to the males swimming belly to belly, inserting the ***** in the other's genital slit and sometimes ****.[52] Odd-toed ungulates (Perissodactyla) Stallions have a vascular *****. When non-erect, it is quite flaccid and contained within the prepuce (foreskin, or sheath). Tapirs have exceptionally long penises relative to their body size.[53][54][55][56] The glans of the Malayan tapir resembles a mushroom, and is similar to the glans of the horse.[57] The ***** of the Sumatran rhinoceros contains two lateral lobes and a structure called the processus glandis.[58] Carnivorans See also: Carnivora § Reproductive system All members of Carnivora (except hyenas) have a baculum.[59] Canine penises have a structure at the base called the bulbus glandis.[60][61] During copulation, the spotted hyena inserts his ***** through the female's pseudo-***** instead of directly through the ******, which is blocked by the false ******* and testes. Once the female retracts her ********, the male enters the female by sliding beneath her, an operation facilitated by the *****'s upward angle.[62][63] The pseudo-***** closely resembles the male hyena's *****, but can be distinguished from the male's genitalia by its greater thickness and more rounded glans.[64] In male spotted hyenas, as well as females, the base of the glans is covered with penile spines.[61][65][66] Domestic cats have barbed penises, with about 120–150 one millimeter long backwards-pointing spines.[67] Upon withdrawal of the *****, the spines rake the walls of the female's ******, which is a trigger for ovulation. Lions also have barbed penises.[68][69] Male felids urinate backwards by curving the tip of the glans ***** backward.[70][71] When male cheetahs urine-mark their territories, they stand one meter away from a tree or rock surface with the tail raised, pointing the ***** either horizontally backward or 60° upward.[72] The male fossa has an unusually long ***** and baculum (***** bone), reaching to between his front legs when erect, with an average thickness of 20 mm (0.79 in). The glans extends about halfway down the shaft and is spiny except at the tip. In comparison, the glans of felids is short and spiny, while that of viverrids is smooth and long.[73] Fossa mating includes a copulatory tie, which may be enforced by the male's spiny *****. This unusually lengthy mating is due to the physical nature of the male's erect *****, which has backwards-pointing spines along most of its length.[74] The male fossa has scent glands near the *****, with the penile glands emitting a strong odor.[73] The beech marten's ***** is larger than the pine marten's, with the bacula of young beech martens often outsizing those of old pine martens.[75] Raccoons have ***** bones which bend at a 90 degree angle at the tip.[76] The extrusibility of a raccoon's ***** can
