Question

The ratio of Neha's age to that of Jane is 4 : 7 and the ratio of Jane's age to that of Smita is 4 : 3. If Smita is 21 years old, how old is Neha?

Answer 1

Answer:

ratio age of jane to smitha = 4:3

let their ages be 4x , 3x

but smitha = 21yrs

=> 3x = 21

=> x = 7

=> jane age = 4x = 4(7 ) = 28yrs

given ratio of neha's age to jane's age = 4:7

let their ages be 4y , 7y

but we've got that jane's age = 28

=> 7y = 28

=> y = 4

∴ Neha's age = 4y = 4(4) = 16yrs
