Question

The total mass of two packets of fruit is 10.5 kg. One packet of fruit is 3 kg lighter than the other. Find the mass of the heavier packet of fruit.

Answer 1

(3+x)+x=10.5

Simplify

2x = 7.5

x = 3.75

Plug in for x

(3 + 3.75) + 3.75 = 10.5

6.75 + 3.75 = 10.5

The heavier packet of fruit is 6.75 kg.
