Question

The Runs scored by M.S Dhoni in 8 innings are given as :

52 , 58 , 64 , 72 , 24 , 8 , x and 112.

If the Average of the 8 innings is 62 , what was his score in the 7th innings.

• A. 116
• B. 86
• C. 96
• D. 106

Answer 1

The correct option is D

106

The score in the 7th innings is denoted as x.

Sum of scores = 52 + 58 + 64 + 72 + 24 + 8 + x + 112 = 390 + x

Total number of scores = 8

Average = $\frac{Sumofscores}{No.ofscores}$

$\Rightarrow$ 62 = $\frac{390+x}{8}$

$\Rightarrow$ 62 $\times$ 8 = 390 + x

$\Rightarrow$ 390 + x = 496

$\Rightarrow$ x = 496 - 390 = 106
