Question

The ratio of present ages of Hema and Chinnu is 13:17. Four years ago the ratio of their ages was 11:15. What will be the ratio of their ages six years hence ?
A) 3 : 7
B) 7 : 9
C) 4 : 5
D) 1 : 3

Answer 1

Answer:

Step-by-step explanation:

given ratio of hema and chinnu is 13:17

let their ages be 13x and 17x

therefore, A/q

13x-4/15x-4  =  11/15

solve the equation,

8x=16

x=2

put the values

age of hema = 13*2 = 26

age of chinnu =17*2 = 34

ages after 6 year

hemu = 26+6=32

chinuu = 34+6=40

their ratio = 4:5
