  1. A batsman has a certain average of runs for 14th innings. He scores 72 runs in the 15th innings, thus his average increased by 2. Find the average after 15th innings.
    1. 44
    2. 46
    3. 42
    4. 48
  1. Correct Option: A

    Let the average of 14th innings = x
    ∴ Average of 15th innings = x+2
    Then, 14x+72 = 15(x+2)
    ⇒ 14x+72 = 15x +30
    ∴ x = 42
    ∴ Average for 15th innings = x+2 = 42 + 2 = 44
