Question

The average of runs of a cricket player of 10 innings was 42. How many runs must he make in his next inning so as to increase his average of runs by 6?

A 94 Correct Answer Incorrect Answer
B 108 Correct Answer Incorrect Answer
C 76 Correct Answer Incorrect Answer
D 150 Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

Let the batsman make x runs. Total runs in 10 innings = 10 × 42 = 420 => (420 + x)/11 = 42 + 6 => 420 + x = 48 × 11 => x = 528 – 420 = 108
