A scored 73, 76, 20 and 7 runs in four out of five innings. What should be his score in fifth innings. If he has to make an average of 55 run in five innings.
Answer & Solution
Correct Answer:
Option
A
Let average of 5th inning is 'x'.
Average of five innings = 55 (Given)
$$\eqalign{ & \frac{{73 + 76 + 20 + 7 + x}}{5} = 55 \cr & 176 + x = 275 \cr & x = 275 - 176 \cr & \therefore \,x = 99 \cr} $$
Average of five innings = 55 (Given)
$$\eqalign{ & \frac{{73 + 76 + 20 + 7 + x}}{5} = 55 \cr & 176 + x = 275 \cr & x = 275 - 176 \cr & \therefore \,x = 99 \cr} $$
