GENPACT Company Numerical Ability Averages

A batsman makes a score of 87 runs in the 17th inning and thus increases his averages by 3.Find his average after 17th inning?
A. 19
B. 29
C. 39
D. 49

Read Solution (Total 3)

let the average after 17th inning =x
Then average after 16th inning=(x-3)
Therefore 16(x-3)+87=17x
Therefore x=39

the increased average has to be distributed in 16 innings i.e 19*3=48
which should be subtracted from 87
87-48=39

Answer is C.39
Avg Increased for all 17 innings so (17*3)=51
Score in 17th inning=87
87-51=36(avg before 17th innings)
so 36+3=39(avg after 17th innings)
