Answer:
The current age of Mark's is 24 years
Explanation:
Given as :
The ratio of sunita's age to Mark's age is 3 : 4
After 12 years the ratio is 5 : 6
So, Let The age of Sunita = 3 x
The age of Mark's = 4 x
∴
=
Or, 6 × ( 3 x + 12 ) = 5 × ( 4 x + 12 )
Or, 18 x + 72 = 20 x + 60
Or, 20 x - 18 x = 72 - 60
Or, 2 x = 12
∴ x =
= 6
So , Let The age of Sunita = 3 x = 3 × 6 = 18 years
The age of Mark's = 4 x = 4 × 6 = 24 years
Hence The current age of Mark's is 24 years Answer
