A batsman makes a score of 87 runs in the 17th inning and thus increases his average by 3. Find his average after 17th inning?

A 35

B 37

C 39

D 41

Solution

Correct Answer: Option C

Let the average after 17th inning = x

Then average after 16th inning = x - 3

then , 16(x-3)+87 = 17x

x = 87 - 48 = 39
