Answer:
14 yrs
Step-by-step explanation:
Let x and y be the present ages of Ramesh and Jyothi.
x + y / 2 = 20 => x + y = 40. ===> equation 1
x + 3 / y - 3 = 3/2
2x + 6 = 3y - 9
2x - 3y = - 15 ===> Equation 2
Solve equations 1 and 2
2x+ 2y = 80
2x - 3y = -15
-------------------
5y = 95
y = 19
Jyoti's present age = 19.
Hence at the time of marriage her age was 19 - 5 = 14 yrs
