Question

A potato seller sells 70% of the total potatoes and still has 150 kg potatoes left with him. Find the weight of the potatoes he had originally

Answer 1

100%-70%=30%

30%=150kg

10%=150/3=50kg

100%=50kg*100=500kg

answer=500kg

Answer 2

Let Total Potatoes = x

Potatoes            %

    x                   100

  150                  30

Cross-multiply

30x = 150 x 100

x = (150 x 100) / 30

x = 500

Therefore, the total potatoes = x = 500 kg
