Question

The directions for a pain reliever recommend that an adult of 60 kg and over take 4 tablets every 4 hours as needed, and an adult who weighs between 40 and 50 kg take only `2 1/2` tablets every 4 hours as needed. Each tablet weighs `4/25` gram. How many grams of pain reliever is the recommended dose for an adult weighing 46 kg?

Answer 1

Given, Adult weighing 46 kg takes `2 1/2` tablets and each tablet weighs `4/25`g.

∴ Total weight of pain reliever, he/she is receiving

= `(4/25 xx 2 1/2)`g

= `(4/25 xx ((2 xx 2) + 1)/2)`g

= `(4/25 xx 5/2)`g

= `2/5`g
