Question : Ram has an average score of 65 runs in 19 innings in cricket matches. Find out how many runs are to be scored by him in the 20th innings to raise the average score to 67.
Option 1: 135
Option 2: 105
Option 3: 115
Option 4: 195
Correct Answer: 105
Solution :
Ram has an average score of 65 runs in 19 innings.
Total runs = Average runs × Number of innings
So, his total runs in 19 innings are (65 × 19) = 1235 runs
To get an average of 67 in 20 innings, he has to score,
[(67 × 20) – 1235] = 1340 – 1235 = 105 runs
Hence, the correct answer is 105.
