Let ABCD be the parallelogram with ∠A = ∠B.
We know: Sum of adjacent angles = 180°
∠A + ∠B = 180º
2∠A = 180º (∠A = ∠B)
∠A = 90º
∠B = ∠A = 90º
∠C = ∠A = 90º (Opposite angles)
∠D = ∠B = 90º (Opposite angles)
Thus, each angle of the parallelogram measures 90º.

(i)After the harvest, the indigo plant was taken to the vats in the indigo factory. Three or four vats were needed to manufacture the dye. Each vat had a separate function.
(ii)The leaves stripped off the indigo plant were first soaked in warm water in a vat, also known as fermenting or steeper vat, for several hours.
(iii)When the plants fermented, the liquid began to boil and bubble. Now the rotten leaves were taken out and the liquid drained into another vat that was placed just below the first vat.
(iv)In the second vat, also known as the beater vat, the solution was continuously stirred and beaten with paddles. When the liquid gradually turned green and then blue, lime water was added to the vat. Gradually the indigo separated out in flakes, a muddy sediment settled at the bottom of the vat and a clear liquid rose to the surface.
(v)This liquid was drained off and the sediment, i.e. indigo pulp transferred to another vat, also known as the settling vat, and then pressed and dried for sale.

Let , Total no.of students study in school = x
Total number of the students in the school come by car = 2x/5
Total number of the students in the school come by bus = x/4
Total number of students walk to school =
x -(2x/5 + x/4 ) =
x- (8x+ 5x) /20 = x-(13x)/20
Total number of students come to school on their own = 1/3×7x/20 = 7x/60
Total number of students come to school on their own = 224 , (given)
x = 224/ 7 × 60
x = 32 × 60
x = 1920
Total number of students study in school = 1920

Let the contribution of third brother be x
Therefore, Contribution of first brother =3x/8
Contribution of second brother = 1x/2
=15x = 480000
Contribution of 3rd brother = x
Contribution of first brother = 3*32000/8
Contribution of second brother = 1*32000/2

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.
The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time.
The third law states that for every action (force) in nature there is an equal and opposite reaction.

First term in this series will be 12. also the last digit will be 248.
the the series will be 12,16,20……….248.
it is a arithmetic series with first term a=12 and common difference of 4.
with last term as 248.
so 248=12+(n-1)x4 (lets assume it has n such numbers.)
so 60 multiples of 4 lie between 10 and 250.

It is an acid-base reaction in which an acid reacts with a base to form salt and water. The pH of the neutralized solution depends upon the acid strength of the reactants and their concentrations. The neutralization reaction is best represented as:
Acid + Base → Salt + Water

One of the known asexual reproduction types is known by the name ‘fragmentation’. As the name is quite self-explanatory, it is a type of cloning where one organism is divided into minor fragments. Once divided, these fragments develop into individual ones which are fully grown.
Fragmentation, also known as a splitting method of reproduction and is seen in many organisms such as cyanobacteria, fungi, many plants, and also in animals including flatworms, sponges, some annelid worms and sea stars.

Non living things are not alive. They do not possess life. They do not have cells and don’t grow or show locomotion/movement. They don’t undergo metabolism with anabolic and catabolic reactions. They do not reproduce.
Non living things do not have a life span. They do not respire as they do not require food for energy and hence do not excrete. They do not fall into any cycle of – born, grow, reproduce and die. They are destroyed or broken down by external force.
Examples of non living things include stone, pen, book, cycle, bottle, etc.

There are days in life that pass by and quickly forgotten because there has been nothing different from the daily routine, and sometimes there are days which stand out like a red letter down the memory lane because they are different from the humdrum of every day life.
One such day was 14th of November when my friend had come from abroad. I was living in Delhi those days and we went sight seeing to a few places there.
The day, fixed for travelling around Delhi, dawned bright and beautiful. It was Saturday and I had taken off from my office. The sun was shining brightly, there was not a shine of clouds in the sky and the chill of winter was off-set by the warmth of the sunshine. We started out on my bike at 10 O’ clock in the morning. The two of us were very excited because we had planned to be out all day and particularly my friend was very enthusiastic about seeing Delhi as it was for the first time she was there.
We came out of the cold and dreary musty smelling atmosphere of the fort and breathed the fresh pure air. Nearby was Humayun’s tomb. We came to know from a guide that Humayun’s dear son had fallen ill and Humayun prayed to Allah to take away his life but save his son. After that he fell ill and wasted away whereas his son became better and better, till finally Humayun died, and his son survived.
After this we went to the boat club at India Gate and hired a boat. The weather was lovely and the two of us were together after a long time. There was a mild breeze blowing and the water was calm with faint ripples as the wind touched the surface. There were people sitting on the grass while we took turns to row the boat. The water was clean and transparent, and I could clearly see our faces in the water. My friend was smiling and seemed very happy. I could also see weeds and sometimes golden fishes swimming around the weeds. The lady sang songs while I joked and laughed and we enjoyed ourselves thoroughly. Then we went off to the children’s park nearby. We both sat on the grass and saw children playing all around till we felt hungry and decided to have our lunch. I had packed a picnic lunch from a restaurant near my place, all snacks and light food. My friend spread out the lunch for both of us. Both of us were really hungry and it was real fun having food out in the open. Little birds and sparrows hopped near by and my friend threw tiny bits of food to them which they would pick.
After resting for a while, I took her to the National Museum nearby. We saw a lot of antique statues hundreds of years old and appreciated the craftmanship of the artisans who worked centuries ago without any of the sophisticated instruments which we now have. We also saw a huge aquarium with all kinds of colourful fishes swimming in and out amongst the weeds and pebbles that had been arranged beautifully inside the huge glass cases. We had a lovely time looking around and the lady had a lot of questions to ask the guide. We finally moved out feeling enlightened but quite tired.
Finally, we made a move to go home. We had spent a lovely day sight-seeing. Together we had seen a lot, learnt a lot, enjoyed a lot and were now happy to go home and relax and talk about everything that we had seen. That evening, we did not take dinner any more as our stomachs were totally full. At about 10 O’ clock we again took a stroll out to have ice-cream. It is very common among Delhiites to walk out of their homes after dinner to enjoy ice-cream. After finishing our ice-cream we walked our way home. That night, we talked to each other for a long time, before going to bed at almost half past 3. Afterall, we had seen each other after five long years. The next morning it was exactly 10 O’ clock when we woke up. It was Sunday and we had no important work, we were very happy to have spent such a wonderful day together. It had indeed been a memorable day which will long remain in our memory.

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.
The following are rational numbers because they are fractions made out of one integer divided by another integer: 1/3, -8/15, 6/31, 8 (or 8/1) The following are also rational numbers because a decimal that stops (terminates) can be written as a rational number: 0.3, -0.25, 0.8976
