The average run rate of a cricket team during the first 20 overs is 3.5. What should be the asking rate per over for the next 30 overs, if it has to chase a target of 325 runs in total?

8.5

Total runs scored in 20 overs = 20 × 3.5 = 70

                   Remaining run = 325 - 70 = 255

                  Run rate/over = \(\frac{255}{30}\) = 8.5
