Question
A boy was asked to multiply a certain number by 25. He multiplied it by 52 and got his answer more than the correct one by 324.The number to be multiplied was
Solution
The problem can be solved by setting up an equation based on the information given in the question.
Let's denote the number that was supposed to be multiplied by 25 as "x".
According to the problem, the boy multiplied this number by 52 instead, and his answer was 324 more than the correct one.
This can be written as:
52x = 25x + 324
To solve for x, we first subtract 25x from both sides of the equation to get:
27x = 324
Then, we divide both sides of the equation by 27 to solve for x:
x = 324 / 27
x = 12
So, the number that was supposed to be multiplied by 25 was 12.
