If 4 Mango and 3 Orange together cost Rs. 3150 and 2 Mango and 4 orange together cost Rs. 2200, then find the difference between 4 mango and 3 orange?
1). 825
2). 700
3). 1650
4). 2350
Let cost of each mango be X and cost of each orange be Y. then we have the following equation from the given data
4x + 3y = 3150 ----(1)
2x + 4y = 2200 ----(2)
To solve these two equation , multiply the second equation by 2 and then subtract one from 2 we get , y = 250
4x + 3(250) = 600
The cost of each mango is Rs. 600 and the cost of each orange is Rs. 250
Then, the cost of 4 mango is 4 × 600 = 2400 and 3 orange is 3 × 250 = 750
∴ Then the difference between 4 mango and 3 orange = 2400 - 750 = 1650
