Question

a batsman has a certain average of runs for 15 innings. in the 17th inning he makes a score of 85 runs there by increasing his average by 3. what is the average after the 17th inning

Answer 1

Let x be the average after 17th innings
So runs scored in all the innings summed is 17x
Runs scored in 16 innings is 16(x-3)
Runs scored in 17th innings is 17x -16(x-3) =
Le x= 39.

Answer 2

Answer:

37 run

Explanation:

Let the average after 17th innings be = x

sum after 17th innings be = 17x

now,

17x = 16(x-3) + 85

17x = 16x - 48 + 85

x = 37 answer
