A boy was asked to multiply a certain number by 25. He, by mistake, multiplied the number by 52 and got the product which was greater than the correct product by 324. The number to be multiplied was:​

Correct option is D

Given:

The boy was asked to multiply a certain number by 25.

He mistakenly multiplied the number by 52 instead, which resulted in a product that was greater by 324. 

Solution:

Let assume that number is X.

​

If the boy multiplies by 25 which is correct then product will be = 25X

​

But boy multiplied by 52

​

In this situation the product is = 52X

​

Now according to the question :

​

=> 52X - 25X = 324

​

=> 27X = 324

​

=> X = 12

​

Hence the correct answer is "12".
