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 kilograms?​

Answer 1

Total wt. = 200000×20 mg

= 4000000 mg

= 4000000/1000 gm

= 4000 gm

= 4000/1000 kg

= 4 kg.

Answer 2

Step-by-step explanation:

Weight of 1 tablet = 20 mg

then, weight of 2,00,000 tablets = 20×200000

= 40,00,000 mg

Now, 1 mg = 1/1000 gm

40,00,000 mg = 4000000/1000

= 4,000 gm

Also, 1 gm = 1/1000 kg

4000 gm = 4000/1000

= 4 kg
