Question

A boy’s batting average for 7 innings is 35 runs. If he scores 27 runs in his next innings,
what is his average now? If he wishes to increase his average to 36 runs, what should be
his score in his 8th innings?

Answer 1

average of 7 innings =35*7
=245
total score and =245+27
average=272
8 34 ans

let x score in the 8 inning
average=36
score in my 8th inning
sum
no =36
245+x = 36
8. 1 we will do crossmultiplecation
245 +x =288
x = 288-245
= 43
therefore his score in 8th inning is 43 runs

Answer 2

total runs scored by the boy in 7 innings = 35×7 =245 runs. If he scores 27 runs in the next innings the total runs will be 245+27=272 and the average will be- 272÷8=34 runs.If he wishes to increase his average to 36 runs, he has to score 43 runs in the 8th innings. 36×8=288-245=43 runs.
