Vivek had an average of 65 in 13 matches. If in one of the matches, he had score 99 instead of 60 runs, what is the new average of Vivek?1). 662). 683). 784). 70

Answer»

Previous average of VIVEK = 65

Total number of matches = 13

Total runs SCORED by Vivek = 65 × 13 = 845

New total of Vivek = 845 – 60 + 99 = 884

∴ New average of Vivek = 884/13 = 68

Alternative method:

Difference between one MATCH in which he had scored 99 and the given average = 99 – 60 = 39

Change in average = 39/13 = 3

Here, difference value is LARGER than the previous value,

∴ New average = Previous average + change in average = 65 + 3 = 68
