Let the current ages of Rahu and Ketu be x and y respectively.
Ratio is 7:5 x:y is 7:5
x/y =7/5
5x=7y
5x-7y=0 --i
After 10 yrs
The ratio is 9:7
(x+10)/(y+10) =9/7
7x+70=9y +90
Solving the above equation.
7x-9y=20—ii
Solve eq-i &eq-ii on both side.
7x-9y=20
5x-7y=0
x=7y/5
substitute the value of X in eq-ii
7*7y/5–9y=20
49y-45y=100
4y=100
y=25
x =7*25/5 = 35
Rahu is 35yrs
Ketu is 25yrs
