    Solution

    ATQ;

    Let the highest and lowest runs scored by Rohit Sharma be ‘x’ and ‘y’ respectively.

    Total runs scored by him in 150 innings = 150 × 80 = 12000

    Runs scored by him in 148 innings = (80 - 2) × 148 = 78 × 148 = 11544

    So, x + y = 12000 – 11544 = 456

    And, x – y = 200

    So, x = (456 + 200)/2 = 328
