Question

the sum of two numbers is 3 times their difference. the ratio of the number is​

Answer 1

Answer:

the sum of two numbers is 3 times their difference

or, x+ y= 2(x-y)

x+y = 2x-2y

3y= x

or, y= x/3

or, y:x = x/3:x= 3:1

Answer 2

Answer:

• Let x and y be the numbers

According to the question

$x + y = 3(x - y) \\ x + y = 3x - 3y \\ y + 3y = 3x - x \\ 4y = 2x \\ \frac{4y}{2} = x \\ \frac{4}{2} = \frac{x}{y} \\ \frac{x}{y} = 2$
