Question

a fruit vendor bought 30 kg of apples and then added 12.8 kg of apples to it. If he sold 40.75kg of apples, how much is left with us

Answer 1

30+12.8=42.8
42.8-40.75
=2.05 kg

Answer 2

a fruit vendor bought apple = 30 kg
then added = 12.8 kg
total weight,
30+12.8 = 42.80 kg
he sold = 40.75 kg
42.80 - 40.75 = 2.05 kg
left apple = 2.05 kg
