Question

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

Answer 1

total tablets = 2,00,000
one tablet weight = 20mg
total weight = 40,00,000mg
total weight in grams = 4000000/1000= 4000g
total weight in kg = 4000000/1000000=4kg

Answer 2

g=4000000/1000=4000g
kg=4000000/1000000=4kg
