A boy was asked to multiply a certain number by 25. He multiplied it by 52 but got his answer more than actual by 324. What is the number?
সমাধান
সঠিক উত্তর: Option A
Let , the number = x
Actual answer = 25x
The wrong answer = 52x
Now, 52x - 25x = 324
or , 27x = 324
or, x = 324/27 = 12
So, the number was 12.
