Question

A cricketer scores 120 runs in his 7th innings after which his average score increases by 5 runs find the average score of his 6 innings

Answer 1

So avg of7 inn= (6x+120)/7
It is given equal to = x+5
On solving x=85

Answer 2

Answer:

85

Step-by-step explanation:

let the average of 6th innings is  "X".

GIVEN: 120 runs in 7th innings and which his average increases by 5 runs.

so,

(x + 120)/7= x+5

x + 120 = 7(x+5)

x + 120 = 7x + 35

7x - x = 120 - 35

6x = 85

this is the average score of his first 6th innings
