Question

Sardines are sold at ₹40 per kg while swordfish at ₹60 per kg. Gracy sold 6 kg Swordfish. Mini has earned as much money as Gracy. How many kg of sardines did Mini sell?

Answer 1

Cost of swordfish per kg = ₹60
Cost of sardines per kg = ₹40

Weight of swordfish sold = 6 kg
Amount of money earned for selling 6 kg of swordfish = 6 × ₹60 = ₹360

It is given that Mini earned as much money as Gracy.
So amount of money earned by Mini by selling sardines = ₹360
Weight of sardines sold = 360 ÷ 40 = 9 kg
