66. A man has some hens and cows. If the number of heads is 48 and the number of feet is 140, then the number of hens will be—

Options:

22

23

24

26

Answer: The correct answer is (4) 26.

Solution: Let the number of hens be hhh and the number of cows be ccc.

Total heads equation: h+c=48 (since each animal has one head).

Total feet equation: 2h+4c=140 (hens have 2 feet, cows have 4 feet).

Now, solve the system of equations:

From equation 1: c=48−h

Substitute into equation 2:

2h+4(48−h)=140

Simplifying:

2h+192−4h=140

Answer: The correct answer is (4) 26.

Directions: Read the following passage and each group of four statements given below contains one statement which is most acceptable in the light of the passage and answer the questions 69 to 71.

When I go into a stranger’s library I round the bookshelves to learn what sort of a person the stranger is and when he comes in I feel that I know the key to his mind and the range of his interests. A house without books is a characterless house, no matter how rich the Persian rugs only tell you whether he has got money, but the books tell you, whether he has got a mind as well. It is not a question of money that we don’t buy books. I repeat that the books are the cheapest as well as the best part of the equipment of a house. You can begin your ‘library’ with the expenditure of a few dollars. Nearly all the best literature in the world is at your command at two dollars a volume. For 100 dollars you can get a library of fifty books. Even if you don’t read them yourself, they are a priceless investment for your children. What delight is there like the revelation of books for the sudden impact of a master-spirit, the sense of window flung wide open to the universe? It is the adventures of mind; the joy of which does not pass away, that give the adventure of life itself, beauty and fragrance.

69. What do the books tell you about a stranger?

That he is a rich man.

That he believes in the priceless investments.

That he has good mental faculty.

71. The word ‘master-spirit’ in the passage means—
