Question

Aleeka is now 12 years old and Ravina is 24 years old. How many years ago was Ravina three times as old as Aleeka​

Answer 1

Step-by-step explanation:

If Aleeka is 12 years old and Ravina is 24 years old then,

Let the required age be x then,

24 - x = 3(12 - x)

=> 24 - x = 36 - 3x

=> 24 - x + 3x = 36

=> 2x = 36 - 24

=> 2x = 12

=> x = 12/2

Hence, x = 6

Answer) Hence, the required age is 6.

Verification :-

If x is 6 then,

24 - 6 = 3(12 - 6)

=> 18 = 36 - 18

=> 18 = 18 [L.H.S = R.H.S]
