16. Scientists have found that tribal people living in rural parts of India
consume rat meat as an important source of protein without falling sick.
However these same individuals if they were to move to a city and
consume rat meat would very likely suffer some illness due to eating rats.
Which of the following provides the best explanation for the statement
that people living in rural areas fall sick if they eat the rats found in cities
but not the rats found in rural areas?
a. The tribal’s from rural areas are not able to buy rats in cities.
b. Rat’s found in rural areas are safe to eat due to the clean rural
environment whereas the rats found in cities are unsafe to eat due to
an unclean urban environment.
c. Tribal’s who move to large cities from rural areas often do not have
much money and so cannot afford to eat meat in large cities, relying
instead on rice as a source of protein.
d. Doctors in large cities are much better than the doctors in rural areas
so tribal’s who move to large cities from rural areas eat rats because
they know that if they fall sick they can go to a good doctor.
e. Eating rat meat in cities is considered a sign of extreme poverty;
because rural people know this they eat chicken and mutton like
everyone else in a city.

Answer Key
1 32. Each successive number is twice the previous number. C.
2 Vikram, Mohit, Rohit, Kunal, Sanjay. A.
3 Fan is the only appliance, all other choices are furniture. D
4 Shoes are worn on the feet; hat is worn on the Head. E.
5 All choices given are vegetables, except Banana. B.
6 Unicycle 1 wheel, Motorcycle 2 wheels, Rickshaw 3 wheels, Car 4 wheels. B.
7 14 chickens, 8 cows, 13 goats, in present year. 14*2= 28, 8*4= 32, 13*4= 52. 28+32+52=112. B.
8 12 people working 8 hours a day take 6 months, so 24 people (twice 12) working 4 hours a day ( ½ of 8) will also take 6 months. A. (Man hours: 12*8=96 and 24*4=96.)
9 Fuel efficient car travels 500 Km in 10 hours, speed equals 50 km/h (500/10), and uses 25 liters of petrol. The same car travels 100 km at the same speed (given in the question), so it will use 5 liters of petrol (Equation: 100/500= x/25). E.
10 Each number is a square of consecutive natural numbers. D.
11 Total cost of all items is 512. Cost of 6 registers is 256. So 512-256=256. 4 pens, 5 pencils, 2 erasers are half of what Sanjay bought, so 256/2= 128. A.
12 Two cars are moving towards each other, so add the speeds (36+64= 100). Distance is 600 Km. Time = distance/speed, 600/100= 6. C.
13 Total length of fence will be 7-1= 6 (draw a diagram and see yourself if it helps). Distance between each pole is 4 feet. 6 * 4= 24. D.
14 Total number of ways to enter will be the product of the 3 main doors and 2 large rooms. 3*2= 6. B.
15 All the numbers in the question are odd, therefore the answer will have an odd number in Unit’s place. All of the answers except d. have an even number in the units place. D.
16 All of the answers except B are irrelevant to answering the question. If the rats in rural area’s are safe to eat because the rural environment is clean and the urban cities are not, then that is why Tribal’s living in cities cannot consume rat meat in cities without falling sick. The question asks why tribal’s get sick in cities if they eat rats, not why they get better, therefore D is also irrelevant. B.
17 Since both the cars are moving in the same direction subtract the speed of the faster one from the slower one 120-60. The faster car is 30 Km behind. So time= distance (30)/speed (60). So time taken is 1/2 hour. E.
18 Dice has 6 sides; with one toss the probability of getting a 3 is 1/6. C.
19 With 2 six sided dice; you will multiply the individual probabilities. So, 1/6*1/6 = 1/36. B.
