divide rs.12540 in a, b and c so that a may receive 3/7 of b and c , and b recieves 2/9 of a and c
------------
Equations:
a + b + c = 12540
a = (3/7)(b+c)
b = (2/9)(a+c)
-------------------
7a - 3b -3c = 0
2a - 9b +2c = 0
a + b + c = 12540
----
Use any method you know to solve to get:
a = 3762
b = 2280
c = 6498
