Question

A box containing 3 oranges, 2 apples, and one banana weighs 15 units. Another box containing 5 oranges, 7 apples, and 2 bananas weighs 44 units. A third box containing 1 orange, 3 apples, and 5 bananas weighs 26 units. How much does each fruit weigh?

Answer 1

Bananas weigh 2, oranges 1, apples 5.

Answer 2

let x be the weight of oranges

let y be the weight of apples

let z be the weight of banana

3x+2y+z= 15

5x+7y+2z = 44

x+3y+5z=26

solve the three equations

x= 1 unit (orange)

y = 5 unit (apple)

z= 2 unit (banana)
