Question

a boy contain 20 mangoes and a girl contain 24 mangoes,if the weight and gain or lose are same then what is the price of one mango?

Answer 1

Answer:

Let apples be denoted by x, mangoes be denoted as y and oranges as z. Then according to the problem we have —

2x+3y+5z=50

⟹3(2x+3y+5y)=3(50)

⟹6x+9y+15z=150

Also we have —

5x+8y+14z=140

Subtracting the boxed equations, we get —

x+y+z=10

Thus the cost of 1 apple, 1 mango and 1 orange is Rs 10.
