Question

One number is three times the other number. The difference between the two numbers is 12. Find the two numbers.

Answer 1

Answer:

The first number will be 9

The second number will be 3

Step-by-step explanation:

Firstly you will have to add 3 and 1 because one of the number is 3 times the other 1 number. So you will get 3.

Then you will multiply 3 by 3 to get 9 since the number is three times the other.

Then you will get 3 and 9.

Answer 2

S O L U T I O N :

$\underline{\bf{Given\::}}$

One number is three times the other number. The difference between the two numbers is 12.

$\underline{\bf{Explanation\::}}$

Let the one number be x & the other number be y respectively.

$\underbrace{\sf{1^{st}\:Case\::}}$

$\mapsto\tt{x = 3y ...............(1)}$

&

$\underbrace{\sf{2^{nd}\:Case\::}}$

$\mapsto\tt{x - y = 12}$

$\mapsto\tt{3y - y = 12\:\:[from(1)]}$

$\mapsto\tt{2y = 12}$

$\mapsto\tt{y =\cancel{12/2}}$

$\mapsto\bf{y = 6}$

∴ Putting the value of y in equation (1),we get;

$\mapsto\tt{x = 3(6)}$

$\mapsto\bf{x = 18}$

Thus,

The two numbers will be 18 & 6 .
