Correct Answer - Option 2 : 16
Solution:
Concept:
Average = (Sum of total score)/(Total innings)
Calculation:
Let be assume before inning was p
Total score of batsman was = 42 × p
Now, total inning is = p + 5
and, total score = 20 + 35 + 25 + 10 + 40 + (42 × p) = 130 + (42 × p)
Now average
⇒ 42 - 5 = [130 + (42 × p)]/(p + 5)
⇒ p = 11
⇒ Total inning he play is = 11 + 5
⇒ 16
∴ The required result will be 16.
