mother:father = 17/18:19/17
mother earns = 17/18 x
father earns= 19/17 x
then, father = mother + 2385
19/17 x = 17/18 x + 2385
on solving, 53x=729810
x=13770
so mother earns = Rs 13005
father earns = Rs 15390
mother earns = 17/18 x
father earns= 19/17 x
then, father = mother + 2385
19/17 x = 17/18 x + 2385
on solving, 53x=729810
x=13770
so mother earns = Rs 13005
father earns = Rs 15390
