Question :26

Sum of eight consecutive numbers of Set A is 376. What is the sum of five consecutive numbers of another set if its minimum number is 15 ahead of average of Set A ?

Answer: (a)

Average of Set A = $376/8 = 47$

Minimum number of second set = 47 + 15 = 62

Hence, required sum = 62 + 63 + 64 + 65 + 66 = 320

Question :27

If an amount of Rs. 15,504 is divided equally among 76 students, approximately how much amount will each student get?

Answer: (a)

Amount received by each student

= $15504/76$ = Rs.204

Question :28

If $(12)^3$ is subtracted from the square of a number the answer so obtained is 976. What is the number?

Answer: (d)

Let the number be x.

∵ $x^2 – (12)^3 = 976$

∴ $x^2 = 976 + 1728 = 2704$

∴ $x = √{2704} = 52$

Question :29

How many pieces of 8.6 metres length cloth can be cut out of a length of 455.8 metres cloth?

Answer: (d)

Number of pieces = $455.8/8.6$ = 53

Question :30

A 3-digit number 4a3 is added to another 3 digit number 984 to give a 4-digit number 13b7 which is divisible by 11. Then, (a + n) = ?

Answer: (b)

Number 1: 4a3
Number 2:984
Number 3:13b7

⇒ a + 8 = b ⇒ b - a = 8

Also, 13b7 is divisible by 11

⇒ 7 + 3 – (b + 1) = 9 – b

⇒ 9 – b = 0 ⇒ b = 9

∴ (b = 9 and a = 1) ⇒ (a + b) = 10
