Question

the average score of a cricketer for ten matches is 42 find the average for last 4 matches

Answer 1

I think 16.8 is the answer

Answer 2

Answer is 34.25

Step-by-step explanation:

*Please check that you haven't given the score of 10 matches as per question, question is incomplete.

Let the total score be  

Total runs in 10 matches = 38.9 $\times$ 10 = 389

Let us calculate now,

Total runs in first six matches = 42 $\times$ 6 = 252

As per question,

total runs in last 4 matches = 389 - 252 = 137

So, score arrives as  

Average for last 4 matches = $\frac {137}{4}$ = 34.25
