Let Nikitha's age 1 year ago = x
Then Jaya's age 1 year ago = 4x
After 6 years their ages are = (4x + 7), ( x + 7)
So,
(4x + 7) - (x + 7) = 9
=> 4x + 7 - x - 7 = 9
=> 3x = 9
=> x = 3
Present age of Jaya = (12+1) years = 13 years
Present age of Nikitha = (3+1) years = 4 years
Ratio of their ages = 13 : 4
