In the first 5 overs of a T-20 international cricket match, the run rate was only 5.6. What should be the run rate (approximately) in the remaining 15 overs to reach a target of 185 runs?
10.46
Runs scored in first 5 overs = 5.6 × 5 = 28
Runs needed in remaining 15 overs = 185 − 28 = 157
Required run rate = 157 ÷ 15 = 10.46
Thus, the correct answer is 10.46.
