A cricketer had a certain average of runs for his 64 innings. In his 65th inning, he is bowled out for no score on his part. This brings down his average by 2 runs. Then what is his new average of runs?
Formula used:
Let the original average be x runs.
Total runs in 64 innings = 64x
New average after 65th inning = x - 2 runs
Total runs in 65 innings = 65(x - 2)
Calculation:
64x = 65(x - 2)
⇒ 64x = 65x - 130
⇒ 130 = 65x - 64x
⇒ 130 = x
New average = x - 2
⇒ New average = 130 - 2
⇒ New average = 128
∴ The correct answer is option (4).
