Explanation Total runs scored by the player in 40 innings = 40 × 50
Total runs scored by the player in 38 innings after excluding two innings = 38 × 48
Sum of the scores of the excluded innings = 40 × 50 - 38 × 48 = 2000 - 1824 = 176
Given that the scores of the excluded innings differ by 172. Hence let's take
the highest score as x + 172 and lowest score as x.
Now x + 172 + x = 176.
=> 2x = 4.
=> x =4/2 = 2.
Highest score = x + 172 = 2 + 172 = 174.
