A batsman scored 98 runs in his 17th match. As a result, his average runs per match increased by 2.5. What was his average before playing the 17th match?
A55.5 ✓ Correct
B60.5
C58.5
D61.5
Correct answer: (A) 55.5
Explanation
The earlier average was 55.5.
Let old average = a over 16 matches.
16a + 98 = 17(a + 2.5).
16a + 98 = 17a + 42.5.
a = 98 - 42.5 = 55.5.
