Direction : The following question is based on the five words given below:
AND FOR THE BIG SUM (The new words formed after performing the mentioned operations may or may not necessarily the meaningful English words.)

information given below and answer the question that follow.
The result of an exam is given below. Out of 1000 students who appeared
(i) 658 failed in Physics
(ii) 166 failed in Physics and Chemistry
(iii) 372 failed in Chemistry, 434 failed in Physics and Maths
(iv) 590 failed in Maths, 126 failed in Maths & Chemistry
Find the number of people who failed in (assuming that none is passed in all subjects.

We have the following equations:
a+ b + c + d + e + f + g = 1000
a + b + d + e = 658, b + d = 166
b + d + c + f = 372
d + e = 434 as in the figure.
d + e + f + g = 590, d + f = 126. Find the values

Direction : Read the following passage carefully and answer the questions that follow by selecting the correct/most appropriate options.
Did you know that there is a fiber that is as flexible and lightweight as nylon yet five times stronger than steel ? Did you know that this fabric is resistant to temperatures higher than 500°F ? Did you know that a woman invented this fiber ? This miraculous fabric is called Kevlar and it is used to make everything from body armor to musical instruments.
The year was 1964. There were gasoline shortages due to conflict in the Middle East. A Polish - American chemist named Stephanie Louise Kwolek was working for DuPont, an American Chemical Company. She and her group were trying to make a lightweight, yet durable fibre to be used in tires. Lighter tires would allow vehicles to get better gas mileage, but the tires had to be strong enough to resist the wear and tear of the road. They had been working on the problem for some time and had little success, until Kwolek had a breakthrough.
Kwolek and her group were synthesizing or creating fibres to test. During one of the steps in the process, Kwolek created a milky white solution by mixing two chemicals that were often used in the process. This solution was usually thrown away, but Kwolek convinced one of the technicians to help her test it. They were amazed to discover that the fabric that Kwolek had created was not only more durable than nylon, it was more durable than steel.
Kwolek had invented Kevlar. Kevlar is a remarkable fabric known for its strength and durability. Since its invention it has found its way into a wide variety of products. Kevlar is used in sporting equipment like bike tires, bowstrings and tennis racquets. It is used in musical instruments like drum heads, reeds and speaker cones. And it is used in protective gear like motorcycle safety jackets, gloves and shoes. However, Kevlar is best known for its ability to stop bullets.
Richard Armellino created the first Kevlar bulletproof vest in 1975. It contained 15 layers of Kevlar, which could stop handgun and shotgun bullets. The vest also had a steel plate over the heart, which made the vest strong enough to stop rifle rounds. Vests like Armellino's were quickly picked up by police forces and it is estimated that by 1990, half of all police officers in America wore bulletproof vests daily. By 2006, there were over 2,000 documented police vest 'saves', or instances where officers were protected from deadly wounds by wearing bulletproof vests.
