9x = 81

x = 9

Answer 2

Given:

Value by which the number was to be multiplied = 32

Value by which the number got multiplied = 23

To find:

The required number.

Solution:

Let us assume that the number is x.

It is said that the number was to be multiplied by 32 but it got to be multiplied by 23 and the answer was less by 81. Thus, the equation will be:

32x = 23x + 81

On simplifying the equation, we get:

32x - 23x = 81

On further simplifying, we get:

9x = 81

x = 9

Thus the required number is 9.
