6.

A number consists of two digits whose sum is 11. If 27 is added to the number, then the digits change their places. What is the number ?

A.

47

B.

65

C.

83

D.

92

Correct answer is A

Let the ten's digit be x. Then, unit's digit = (11 - x).

So, number = 10x + (11 - x) = 9x + 11.

Therefore (9x + 11) + 27 = 10 (11 - x) + x ⇔ 9x + 38 = 110 - 9x ⇔ 18x = 72 ⇔ x = 4.

Thus, ten's digit = 4 and unit's digit = 7.

Hence, required number = 47.

A monkey climbs 30 feet at the beginning of each hour and rests for a while when he slips back 20 feet before he again starts climbing in the beginning of the next hour. If he begins his ascent at 8.00 a.m., at what time will he first touch a flag at 120 feet from the ground?

A.

4 p.m.

B.

5 p.m.

C.

6 p.m.

D.

None of these

Correct answer is C

Net ascent of the monkey in 1 hour = (30 - 20) feet = 10 feet.

So, the monkey ascends 90 feet in 9 hours i.e. till 5 p.m.

Clearly, in the next 1 hour i.e. till 6 p.m. the monkey ascends remaining 30 feet to touch the flag.

8.

In a caravan, in addition to 50 hens, there are 45 goats and 8 camels with some keepers. If the total number of feet be 224 more than the number of heads in the caravan, the number of keepers is

A.

5

B.

8

C.

10

D.

15

Correct answer is D

Let number of keepers be x. Then,

Total number of feet = 2 x 50 + 4 x 45 + 4 x 8 + 2x = 2x + 312.

Total number of heads = 50 + 45 + 8 + x= 103 + x.

Therefore (2x + 312) = (103 + x) + 224 or x = 15.

9.

A group of 1200 persons consisting of captains and soldiers is travelling in a train. For every 15 soldiers there is one captain. The number of captains in the group is

A.

85

B.

80

C.

75

D.

70

Correct answer is C

Clearly, out of every 16 persons, there is one captain. So, number of captains (1200/16) = 75.

10.

After distributing the sweets equally among 25 children, 8 sweets remain. Had the number of children been 28, 22 sweets would have been left after equal distribution. What was the total number of sweets ?

A.

328

B.

348

C.

358

D.

Data inadequate

Correct answer is C

Let the total number of sweets be (25x + 8).

Then, (25x + 8) - 22 is divisible by 28

⇔ (25x - 14) is divisible by 28 ⇔ 28x - (3x + 14) is divisible by 28

⇔ (3x + 14) is divisible by 28 ⇔ x = 14.

Therefore Total number of sweets = (25 x 14 + 8) = 358.
