Madhya Pradesh Police Exam Model Paper 1

GIVEN:
Aslam gets a score of 108 runs in his ${23}^{\mathit{r}\mathit{d}}$ inning and this score increases his average by 2 runs.
CONCEPT:
Basic average concept.
FORMULA USED:
Average = Sum of numbers/Total numbers
CALCULATION:
Let the average of Aslam after 23 innings be ‘x’
So,
$22\times \left(\mathit{x}\mathit{–}2\right)+108=23\mathit{x}$
$\Rightarrow 22\mathit{x}\mathit{–}44+108=23\mathit{x}$
$\Rightarrow \mathit{x}=64$
Hence, Average of Aslam after 23 innings = 64
