Question

Leena loves peanut butter. Today, she ate four tablespoons of it. If there are 6 mg of vitamin E in four tablespoons of peanut butter, what percentage of the vitamin E RDA did Leena consume through peanut butter?

Answer 1

The recommended dietary allows differs with age, sex, and health status. Leen is an healthy female adult so the RDA should be 15 mg so if she has consumed 6 mg the percentage is 6/15*100 = 40%

Answer 2

Answer: If Leena is taking 4 tablespoon of peanuts that means her age is above 15 years and the recommended daily allowance (RDA) given by the National Institute Of Health (NIH),for an adult female is 15 mg of vitamin E a day.

If 4 tablespoon of peanut butter contains 6 mg of Vitamin E then she consumed:

                               6/15*100=40%

Hence, from this solution we can conclude that she took 40% of vitamin E according to the RDA.
