Question

The cost of 4 rings and 2 bangles is 57200 what is the cost of 6 rings and 3 bangles

Answer 1

4r+2b=57200
2r+b= 28600

multiply by 3
6r+3b=85800

Answer 2

Let cost of 1 bangle be x & let cost of 1 ling be y.

2x + 4y = 57200.

Div by 2 on both sides.

x + 2y = 28600

3x + 6y = 3(x+2y) = 3*28600 = 85800 Rs
