Question

The present ages of amit and sumit are in the ratio of 1:2. Four years later, their ages will be in the ratio of 7:13. What is their present ages?

Answer 1

Answer:

Present age of amit is 24 yrs and sumit is 48 yrs

Step-by-step explanation:

Let the present age of amit be x and sumit be y

X:y=1:2.......(1)

(X+4):(y+4)=7:13.......(2)

X/y=1/2

Y=2x......(3)

X+4/y+4 =7/13

7(y+4)=13(x+4)

7y+28=13x+52

7y-13x=52-28

7y-13x=24

Putting value of y

7(2x)-13x=24

14x-13x=24

X=24yrs

Y=48yrs
