A batsman has a certain average of runs for 14th innings. He scores 72 runs in the 15th innings, thus his average increased by 2. Find the average after 15th innings.
-
- 44
- 46
- 42
- 48
Correct Option: A
Let the average of 14th innings = x
∴ Average of 15th innings = x+2
Then, 14x+72 = 15(x+2)
⇒ 14x+72 = 15x +30
∴ x = 42
∴ Average for 15th innings = x+2 = 42 + 2 = 44
