9 people contribute Rs. 45 each. 3 leave. What amount must each pay now to keep total same?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Rs. 67.5.
First find the original total contribution:
9 people × ₹45 = ₹405
Now 3 people leave, so remaining people = 9 − 3 = 6
To keep the total same (₹405), each of the 6 people must pay: ₹405 ÷ 6 = ₹67.5
