Two Mangoes, three grapes and four apples cost Rs. 15. Three Mangoes, two grapes and one apple cost Rs. 10. I bought 3 Mangoes, 3 grapes and 3 apples. How much did I pay?

Rs15

Rs18

Rs20

Rs25

Explanation:

Mango=X;. Grape = Y; Apple =Z ;
2X+3Y+4Z= 15— 1
3X+2Y+Z= 10— 2
Adding (1) and (2) 5X+5Y+5Z= 25
Clearly, X+ Y+Z = 5.
So cost of 3 Mangoes, 3 grapes and 3 apples will be 3X+3Y+3Z i.e, 15
