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

Answer:

Weight of one tablet = 20 mg

Weight of a box of medicine tablets containing

2,00,000 tablets \[=2,00,000\times 20\text{ }mg\]

Total weight of all tablets in gram

\[=\frac{2,00,000\times 20\,g}{1000}\]

\[=4000\,g\]

\[\because \]                   \[1\,kg=1000\,\,gm\]

\[\therefore \]      Total weight of all tablets in kilograms

\[=\frac{4000\,kg}{1000}\]

\[=4\,\,kg\]
