Correct Answer - Option 3 : 62
Given:
The average score of a batsman after his 50th innings was 46.4
Formula used:
Average = Sum of all number/Total number of values
Calculation:
Let the runs after 50th innings be x
And the runs after 60th innings be y
⇒ x/50 = 46.4
⇒ x = 2320 ----(1)
And Y the runs after 60th innings,
⇒ y/60 = (46.4 + 2.6)
⇒ y = 2940 ----(2)
Subtract form equation(2) to equation(1);
⇒ x – y = 2940 – 2320
⇒ x – y = 620
620 is the runs scored by batsman in last 10 innings,
Average score = 620/10
⇒ 62
∴ The average score in the last ten innings is 62.
