Question

The diff between 2 positive integers is 30.The ratio of these integers is 2:5 find the integers

Answer 1

Answer:

Let the two numbers be 'x' and 'y'

» x-y=30 .....equ(1) (Given)

and x/y=2/5 ...equ(2) (Given)

x = 2y/5

substitute in equ(1)

» 2y/5 -y=30

or, (2y-5y)/5 = 30

or, (-3y) = 150

or, (-y) = 50

or, y = -50

substitute it in equ(2)

x=2y/5

or, x = 2(-50)/5

Or, x = 2(-10) = -20

Therefore, the two integers are -20 and -50
