Which of the following numbers are co-prime: (a) 18 and 35 (b) 15 and 37 (c) 30 and 415 (d) 17 and 168 (e) 216 and 215 (f) 81 and 16
Ans:
A Co-prime number is a set of numbers or integers which have only 1 as their common factor i.e. their highest common factor (HCF) will be 1.
(a)
Factors of 18 = 1, 2, 3, 6, 9,18
Factors of 35 = 1, 5, 7, 35
Common factor of 18 and 35 = 1
Since both have only one common factor, i.e., 1, therefore, they are co-prime numbers.
(b)
Factors of 15 = 1, 3, 5,15
Factors of 37 = 1, 37
Common factor of 15 and 37 = 1
since both have only one common factor, i.e., 1, therefore, they are co-prime numbers.
(c)
Factors of 30 = 1, 2, 3, 5, 6, 15, 30
Factors of 415 = 1, 5, 83, 415
Common factor of 30 and 415 = 1,5
Since both have more than one common factor, therefore, they are not co-prime numbers
(d)
Factors of 17 = 1, 17
Factors of 68 = 1, 2, 4, 17, 34, 86
Common factor of 17 and 68 = 1, 17
Since, both have more than one common factor, therefore, they are not co-prime numbers
(e)
Factors of 216 = 1, 2, 3, 4, 6, 8, 36, 72, 108,216
Factors of 215 = 1, 5, 43, 215
Common factor of 216 and 215 = 1
Since, both Have only one common factor, i.e , 1 , therefore they are co-prime numbers.
(f)
Factors of 81 = 1, 3, 9, 27, 81
Factors of 16 = 1, 2, 4, 8, 16
Common factor of 81 and 16 = 1
Since both have only one common factor, i.e., 1, therefore, they are co-prime numbers.

(ii) Four limbs are modified into wings.
(iii) Wings have long quill feathers to increase the efficiency of heating of wings,
(iv) Pneumatic bones are present to reduce the body weight.
(v) High metabolic rate to provide energy.

Flight adaptations in birds
(i) Boat-shaped body helps to propel through the air easily.
(ii) Feathery covering of body to reduce the friction of air.
(iii) Holding the twigs automatically by hindlimbs.
(iv) Extremely powerful muscles that enables the wings to work during flight.
(v) Bones are light, hollow and provide more space for muscle attachment. Presence of pneumatic bones which reduce the weight of body and help in flight.
(vi) The first four thoracic vertebrae are fused to form a furculum for walking of the wings.
(vii) Lungs are solid and elastic and have associated air sacs.
(viii) The power of accommodation of eyes is well developed due to the presence of comb-like structure pecten. (ix) A single left ovary and oviduct to reduce the body weight.

2√3x2 ˗ 5x + √3
⇒ 2√3x2 ˗ 2x ˗ 3x+ √3
⇒ 2x (√3x ˗ 1) ˗ √3 (√3x ˗ 1) = 0
⇒ (√3x ˗ 1) or (2x − √3) = 0
⇒ (√3x ˗ 1) = 0 or (2x − √3) = 0
⇒ x = 1/ √3 or x = √3/ 2
⇒ x = 1/ √3 × √3 /√3 = √3/ 3 or x = √3/ 2

The LCM of 3,6,9,12 is 36.
2/3=2×12/3×12=24/36
1/6=1×6/6×6=6/36
5/9=5×4/9×4=20/36
7/12=7×3/12×3=21/36
So, Ascending order = 6/36<20/36<21/36<24/36
=1/6<5/9<7/12<2/3

The law of variable proportion states that as we increase the quantity of only one input, keeping other inputs fixed, the total product increases at an increasing rate (convex shape) in the beginning, then increases at diminishing rate (concave shape) and after a level of output ultimately falls.

2. Assumptions of Law of Variable Proportions
(a) Only one input is variable, the other is held constant or fixed.
(b) It is possible to change the proportion in which the factor units are combined.
(c) It assumes a short run.
(d) The state of technology is given and remains unchanged.
(e) Price of factors of production do not change.
3. It can be explained with the help of schedule and diagram:
