Now, as batsman in 17 innings he makes a score of 85 runs. As, it is given that in 17 innings he makes a score of 85 runs thereby increasing his average by 3. Then, $\dfrac{16A+85}{17}=A+3$ , where 17 is total number of innings, 16A + 85 is total score till 17 innings and A + 3 is average of 17 innings.
