Question

5 years ago aryan is a thrice old as rohan tan years later aryan was twice as old as rohan how old are aryan and rohan​

Answer 1

Step-by-step explanation:

let the present age of Rohan be X and Aryan be y

5 years ago,

Aryan age is x-5

Rohan age is y-5= 3(x-5)

y=3x-15+5

y=3x-10--------(1)

10 years later,

Aryan age is X+10

Rohan age is y+10=2(X+10)

y=2x+20-10

y=2x+10--------(2)

from 1 and 2,

3x-10=2x+10

3x-2x=10+10

X=20

but,y= 2x+10= 2(20)+10= 50

therefore,

Rohan age is 20 and

Aryan age is 50
