Question

A box of medicine tablets contains 2,00,000 tablets each weighing 20 mg. What is the total weight of all the tablets in the box in grams? In kilograms?

Answer 1

∵ Each tablet weighs = 20 mg

∴ The weight of 2,00,000 tablets = 2,00,000 × 20 = 40,00,000 mg
​ ∴ The total weight of all the tablets in the box = 40,00,000 mg

We know 1 g = 1,000 mg
∴ Weight of the box having all tablets = 40,00,000 ÷ 1,000 = 4,000 g

And, as 1 kg = 1,000 g
∴ Weight of the box having all tablets = 4,000 ÷ 1,000 = 4 kg
