Question

the ratio of the present ages of two brother is 1:2 and 5 years back ratio was 1:3what will be the ratio of their ages after 5 years​

Answer 1

Answer:

11:17

Step-by-step explanation:

Let the two brothers be x and y

x:y=1:2

present age of x = a

present age of y = 2a

5 years back,

(a-3):(2a-3) = 1:3

a-3/2a-3= 1/3

3a-9= 2a-3

3a-2a= -3+9

a=6

The ratio of x and y after 5 years

(a+5):(2a+5)

(6+5):(12+5)

11:17 (Ans)
