Correct Answer - Option 4 : 70.5
GIVEN:
the average score of twenty-five matches = 75 runs
In the next five-matches score = 240.
FORMULA USED:
Average = Sum of numbers/Total numbers
CALCULATION:
Total runs till twenty-five matches = 25 × 75 = 1875
So,
New average = [1875 + 240]/30 = 2115/30
New average = 70.5
