Question

the ages of sonu and monu are in the 5:7.if sonu were 9 years older and monu 9 years younger, the age of sonu would have been twice the age of monu.find their present age

Answer 1

Step-by-step explanation:

let's take their ages as 5x and 7x

therefore,sonu is older than monu so the equation is

5x+9+7x-9=9

5x+7x=9-9+9

12x=9

x=9/12

x=3/4
