ArithmeticAverages & Ages
The average of runs of a cricket player of 10 innings was 32. How many runs must he make in his next innings so as to increase his average of runs by 4?
- a.76
- b.70
- c.4
- d.2
Answer: (A) 76
He has 10 × 32 = 320 runs; an average of 36 over 11 innings needs 396 runs. So the next innings must bring 396 − 320 = 76 runs. Option C, 4, is only the rise wanted in the average, not the runs he must score.
