Question

Jane went on a diet, and her mass went from 60 kg to 54 kg. What was the 5 points percentage decrease in her mass?

a) 5%
b) 9%
c) 10%
d) 15%

Answer 1

The 5 points percentage decrease in Jane's mass is 10%.

Step-by-step explanation:

To find the percentage decrease in Jane's mass, we need to calculate the difference between her initial mass and her final mass, and then express that difference as a percentage of her initial mass.

Initial mass = 60 kg

Final mass = 54 kg

Difference = Initial mass - Final mass = 60 kg - 54 kg = 6 kg

Percentage decrease = (Difference / Initial mass) * 100

Percentage decrease = (6 kg / 60 kg) * 100 = 10%

Therefore, the 5 points percentage decrease in Jane's mass is 10% (option c).
