The average of runs scored by a player in 22 innings is 40 runs. How many runs should he score in the 23rd innings so that his average is increased by 6 runs?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 178 runs.
Average after 22 innings = 40
Total runs in 22 innings = 22 × 40 = 880
New average after 23 innings = 40 + 6 = 46
Total runs needed for 23 innings = 23 × 46 = 1058
Runs needed in 23rd innings = 1058 − 880 = 178
