Time for some questions on simple arithmetic!

A health and wellbeing shop has the following coding system for pre-made protein drinks. They are graded by the protein content in grams per shake. They have listed the number of each that they have in stock.

Drinks with more protein tend to be priced at a higher level when they are not on special offer. The brand ProtoShake runs deals every third week with up to 75% off their normal price.

1. What proportion of the drinks stocked have fewer than 15g of protein in the shake?
  • 7
    0

    Explanation

    Answer: C

    Explanation:

    1. Find the number of drinks stocked with this protein and thus the proportion:

    Proportions consider a value as a percentage of the total:
    For this question, it is the number stocked with less than 15g of protein as a percentage of the total number stocked:

    There are 10 with <10g protein and 17 with 10-14.9g:

    10 + 17 = 27

    There are 80 in total:
    10 + 17 + 12 + 41 = 80

    27/80 = 0.3375 = 33.75%
