Answer 1

Step-by-step explanation:

Given :-

If we add 9 to a number and then multiply by 12 the product is 324 .

To find :-

What was for original number?

Solution :-

Let the original number be X

On adding 9 to it then it becomes X+9

On multiplying (X+9) with 12 then the result

=> (X+9)×12

=> (X×12)+(9×12)

=> 12X+108

According to the given problem

The result = 324

=> 12X+108 = 324

=> 12X = 324-108

=> 12X = 216

=> X = 216/12

=> X = 18

Therefore X = 18

Answer:-

The Original number for the given problem is 18

Check:-

The number = 18

On adding 9 => 18+9 = 27

On multiplying with 12 then

=> 12×27

=> 324
