Best answer
Correct Answer - Option 4 : 24

Given: A cricketer scored 48 runs in the 7th innings. His average score increased by 4.

Formula: Average of n numbers a1, a2, ... an = (a1 + a2 + ... + an)/n

Calculation: Let his average up to 7th innings be x

(6x + 48)/7 = x + 4

⇒ 6x + 48 = 7x + 28

⇒ 20 = x

So, his average after 7th innings is 20 + 4 = 24
