Question

A cricketer had a certain avg of runs in 80innings. In his 81st innings he is bowled out for no score due to which his avg falls by 1 run . Find his new avg runs

Answer 1

New average is 81,81 runs is the Ans

Answer 2

His new average runs is 80.

Step-by-step explanation:

Let average of runs be 'x'.

Number of innings = 80

If in his 81 st innings he is bowled for no score, his average falls by 1 run.

So, according to question, we get that

$\dfrac{80x+0}{81}=x-1\\\\80x=81(x-1)\\\\80x=81x-81\\\\80x-81x=-81\\\\-x=-81\\\\x=81$

So, the new average would be

x-1=81-1=80

Hence, his new average runs is 80.
