Question

The difference between two numbers is 12. Three times the larger number is nine times the smaller. Find the two numbers.

Answer 1

Hi ,

Let one number = x

Second number = x - 12

According to the problem given ,

3x = 9 ( x - 12 )

3x = 9x - 108

3x - 9x = - 108

- 6x = - 108

x = ( - 108 ) / ( - 6 )

x = 18

Therefore ,

Required two numbers are

x = 18 ,

Second number = x - 12

= 18 - 12

= 6

I hope this helps you.

Answer 2

i think solution would be like this-

let the no. be x
1) no. 3x
2)no. 9x

according to the question
9x-3x=12
3x=12
x=12÷3=4
