Question

A batsman scored at an average some runs in 10 innings. He scored 48 runs in the 11th innings. Thereby his average runs came down by 2. What were his average runs in 11 innings ?​

Answer 1

Answer:

68

Step-by-step explanation:

Let n be average run of batsman in 10 innings

In 11th inning it average run is( 10n +48)/11

From given condition

( 10n +48)/11=n-2

10n+48=11n-22

n=70

So it's average run in 10 innings is 70

For 11th innings

Average run= (700+48)/11=68
