Question

Ajit tendulkar has a certain average for 9 innings in the tenth innings he scores 100 runs there by increasing his average by 8 runs his new averageis?

Answer 1

Answer:

28

Step-by-step explanation:

Let Ajit's average be x for 9 innings. So, Ajit scored 9x run in 9 innings.

In the 10th inning, he scored 100 runs then average became (x+8). And he scored (x+8)*10 runs in 10 innings.

Now,

⇒9x+100=10×(x+8)

9x+100=10x+80

10x - 9x=100−80

x=20

Newaverage (x+8)=20+8 runs

= 28 runs
