Bangladesh Bank - Assistant Director - 2015

A. 216
B. 125
C. 100
D. 64

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

To find the total amount if each of the six members of a family gives money as per their membership number, you can sum up their membership numbers.

The membership numbers are typically 1, 2, 3, 4, 5, and 6 for the six members.

Now, add these numbers together:

1 + 2 + 3 + 4 + 5 + 6 = 21

So, the total amount would be 21. However, the answer choices provided are not correct. The total amount should be 21

not 216, 125, 100, or 64. It appears there might be an error in the answer choices.
