A cricketer has a certain average in 9 innings. In the 10th innings he scored 100 run and thus increases his average by 8 runs. What is his new average?
A. 28
B. 29
C. 30
D. 24
সঠিক উত্তরঃ
A.
28
Explanation: Let initial average be (x). Total runs in 9 innings = (9x).
After 10th inning: ((9x + 100) / 10 = x + 8)
(9x + 100 = 10x + 80)
(x = 20).
New average = (20 + 8 = 28).
