Question

A batman makes a score of 85 runs in the 17 th inning and thus increses his average by 3 , then find his average run.

Answer 1

Solution

Average of 16 innings $=x$

$\therefore$ From the question,

$$

\begin{aligned}

16 x+85 &=17(x+3) \\

\Rightarrow \quad 16 x+85 &=17 x+51 \\

\Rightarrow \quad 17 x-16 x &=85-51=34

\end{aligned}

$$

$$

\therefore \quad x=34

$$

$$

\begin{array}{l}

\therefore \text { Required average } \\

=34+3=37: \text { Ans. }

\end{array}

$$
