Question

The average score of a batsman after his 50th innings was 46.4. After 60th innings, his average score increases by 2.6. What was his average score in the last ten innings? 

(a) 122

(b) 91

(c) 62

(d) 49

Answer 1

Correct option is (c) 62

Total runs scored by the batsman in 50 innings = 50 × 46.4 = 2320.

Total runs scored by the batsman in 60 innings = 60 × (46.4 + 2.6) = 2940.

Total runs scored in last 10 innings = 2940 - 2320 = 620.

Average score in last 10 innings = \(\frac{620}{10}\) = 62.
