How many persons are standing in the row?

A. The number of persons in the row is between 60 to 110.

B. The number persons in the row is a perfect square and for one person in the queue the number of persons in front of him is equal to the number of persons behind him.

Answer: 3

Solution: A alone cannot conclude.

From B we know the number is a perfect square. Combining it with A, it can be 64, 81 or 100. But as one person has equal numbers before and after, the number should be odd. Hence only 81 is odd.

Thus 3 is the answer.

40. A hollow cube of length 5 cm is taken, with a thickness of 1 cm. It is into smaller cubes of size 1 cm. Initially if 2 faces of the outer surface of the bigger cube were painted, how many faces of the smaller cubes remain unpainted?

Answer: 538

Solution: Volume of the bigger hollow cube = 5*5*5 - 3*3*3 = 125-27 = 98 cubic cm.

Number of 1 cm cubes = 98/(1*1*1) = 98

Total number of faces = 98*6 = 588

As two faces of the bigger cube are painted, total faces painted in smaller cubes = 2*25=50.

Hence number of faces not painted = 588-50 = 538

(16 ÷ 8 × 6 – 2 + 12) = (16 + 8 – 6 × 2 ÷ 12)

= 16 + 8 – 6 × (1/6)

= 16 + 8 – 1 = 24 – 1 = 23.
