Let Ram and Ravan's age be x and y respectively
x-1/y-1=5/6
6x-6=5y-5
6x-5y-1=0.......(1)
x+4/y+4=6/7
7x+28=6y+24
7x-6y+4=0......(2)
Multiplying (1) with 6 and(2)with 5 we get:
36x-30y-6=0.....(3)
35x-30y+20=0.....(4)
Subtracting (3) and (4):
x=26
7x-6y+4=0
=6y=7*26+4
=6y=186
=y=31
So Ram's age is 26
Ravan's age =31
