Question: 1

A batsman in his 17th innings, makes a score of 85 runs, and thereby, increases his average by 3 runs. What is his average after the 17th innings? He had never been ‘not out’.

(A) 37

(B) 43

(C) 47

(D) 53

Ans: A

Average score before 17th innings = 85 - 3 × 17 = 34

∴ Average score after 17th innings = 34 + 3 = 37.

Question: 2

The average temperature from Monday to Thursday is 48°C and from Tuesday to Friday is 52°C. If the temperature on Monday is 42°C. What was it on Friday?

(A) 51°C

(B) 52°C

(C) 55°C

(D) 58°C

Ans: D

Temperature on Monday + Tuesday
+ Wednesday + Thursday = 4 × 48° = 192°

Temperature on Monday = 42°

∴ Tuesday + Wednesday + Thursday + Friday = 4 × 52° = 208°

∴ Friday’s temperature = 208° - 150° = 58°

Question: 3

If the average marks of three batches of 55, 60 and 45 students respectively is 50, 55 and 60, then the average marks of all the students is

(A) 39.68

(B) 53.33

(C) 54.68

(D) 55

Ans: A

Average marks of all students

= $${55 × 50 + 60 × 15 + 45 × 60} / {160}$$

=$${55 × 5 + 6 × 15 + 45 × 6} / {16}$$

= $${275 + 90 + 270} / {16}$$ = $${635} / {16}$$ = 39.68.

Question: 4

The average age of 35 students in a class is 16 years. The average age of 21 students is 14. What is the average age of remaining 14 students?

(A) 15 years

(B) 17 years

(C) 18 years

(D) 19 years

Ans: D

Average age of 35 students = 16

Average age of 21 students = 14

∴ Average age of remaining 14 students = $${35 × 16 - 21 × 14} / {14}$$

= 5 × 8 - 21 = 40 – 21 = 19 years.

Question: 5

(B) 25200

(D) 48000

Ans: D

Total monthly salary of 21 persons = Rs. (21 × 2000) = Rs. 42000

Total monthly salary of 20 persons = Rs. (20 × 1900) = Rs. 38000

Monthly salary of the manager = Rs. 4000

Annual salary of the manager = Rs. 48000
