Question

Brian has reduced his cholesterol level by 20% by following a strict diet and regular exercise. If his original level was 220, what is his cholesterol level now?

Answer 1

220 x 20% (.20) = 44
220-44=176

Answer 2

Option B is the answer.

Explanation:

Actual cholesterol level of Brain was 220.

He reduced his cholesterol level by 20% By following a strict diet and regular exercise.

So we have to calculate current level of his cholesterol.

Since 20% of 220 =
`(220*20)/(100)` = 44

So after reduction of 44 units cholesterol level will be 220 - 44 = 176

Option B 176 is the answer.
