Madhya Pradesh Police Exam Model Paper 4

Given:
Score in 16th innings is 120
Increase in average is 6
Formula Used:
Total score = Average × No. of Innings
Calculations:
Let the initial average be ‘k’
⇒ New average $=\mathit{k}+6$
⇒ Total Score after 15 innings $=15\mathit{k}$
⇒ Total Score after 16 innings $=16\left(\mathit{k}+6\right)=16\mathit{k}+96$
$\Rightarrow 15\mathit{k}+120=16\mathit{k}+96$
$\Rightarrow \mathit{k}+6=30$
∴ New Average $=\mathit{k}+6=30$
