Virat Kohli made 160 runs in his 16th innings, and after that his average increased by 5. Find his average after 16 innings.

1. 80
2. 85
3. 75
4. 60

Correct answer: 85

Solution

Let the average after 16 innings be \(x\). Then the average after 15 innings was \(x-5\). Using total runs: \(15(x-5)+160=16x\). Solving gives \(15x-75+160=16x\), so \(x=85\).
