Question:

A batsman's average after $12$ innings is $42$. How many runs must he score in the $13^{\text{th}}$ innings to raise his average to $45$? / एक बल्लेबाज़ का $12$ पारियों के बाद औसत $42$ है। अपना औसत $45$ करने के लिए उसे $13$वीं पारी में कितने रन बनाने होंगे?

1.
75 / 75
2.
81 / 81
3.
87 / 87
4.
93 / 93

Correct Answer: 81 / 81

Runs needed $= 13 \times 45 - 12 \times 42 = 585 - 504 = 81$. (The trap answer $75$ comes from $45 + 30$, mixing the new average with the old total.) / आवश्यक रन $= 13 \times 45 - 12 \times 42 = 81$।
