Solutions to the Above Questions with Solutions

Solution 1: 4)

Sum of 12 numbers = 12 × 30 = 360

Sum of first 7 numbers = 7 × 24 = 168

Sum of last 4 numbers = 4 × 36 = 144

8^th number = 360 – 168 – 144 = 48

Hence, option d.

Solution 2: 2)

Total weight of 25 students = 25 × 50 = 1250 kg

Total weight of 25 students and class teacher together = 26 × 51 = 1326 kg

Weight of the teacher = 1326 – 1250 = 76 kg

Hence, option b.

Solution 3: 3)

Let average price of each storybook bought was Rs. x

Total price of 50 storybooks = Rs. 50x

According to question;

(50x + 76)/(50 + 14) = (x – 1)

50x + 76 = 64x – 64

14x = 140

x = 10

Hence, option c.

Solution 4: 4)

New average = {(25 × 24) – 27 – 48 – 65 + 75 + 32 + 43}/25 = 24.4

Hence, option d.

Solution 5: 2)

Let the average age of each person before replacement be ‘x’ kg

Sum of the ages of 30 persons before replacement = 30x

Sum of the ages of 30 persons after replacement = 30(x + 1)

Let the weight of the new person be ‘y’ kg

According to the question,

30x – 75 + y = 30(x + 1)

Or, y = 30 + 75

Or, y = 105 kg

Hence, option b.

Solution 6: 4)

Correct sum of the ages of 25 boys = (25 × 24) – 18 – 24 + 12 + 20 = 590 years

Required average = 590/25 = 23.6 years

Hence, option d.

Solution 7: 1)

According to question: 21x + 87 = 22 × (x + 1.5)

x = 87 – 33

x = 54

So total runs scored till 22 innings = 55.5 × 22 = 1221

Hence, option a.

Solution 8: 3)

Required average = {(80 × 35) – 55 – 45 + 75 + 85}/65 = 44

Hence, option c.

Solution 9: 2)

Let the four numbers be A, B, C and D respectively.

According to question;

3A + B + C + D = 3 × 348 = 1044 —(1)

3B + C + D + A = 3 × 380 = 1140 —–(2)

3C + D + A + B = 3 × 420 = 1260 ——(3)

3D + A + B + C = 3 × 364 = 1092 ——(4)

Adding (1), (2), (3) and (4), we get

6 × (A + B + C + D) = 4536

A + B + C + D = 756

So, we get A = 144, B = 192, C = 252 and D = 168

Hence, option b.

Solution 10: 4)

The average of a, b, c, d, e, f, g is ‘d’.

And, the average of j, k, l, m, n is ‘l’.

Required average = (7d + 5l)/12

Hence, option d.
