Question

two apples and three mangoes cost Rs. 86 four apples and one mango cost Rs. 112 what is the cost of an apple?

Answer 1

2 apples + 3 mangoes = Rs 86   ------------ [ 1 ]

4 apples + 1 mangoes = Rs 112   ------------ [ 2 ]

Equation [ 1 ] x 2 :

4 apples + 6 mangoes = Rs 172 ------------ [ 3 ]

Equation [ 3 ] - [ 2 ] :

5 mangoes = Rs 60

1 mango = 60 ÷ 5 = Rs 12 ------------ Sub into [ 2 ]
