Question

Misha increased her test score from 60% to 80%.
What was the approximate percent increase of Misha's test score?
25%
33%
66%
75%

Answer 1

33% because let's assume that the test was out of 100.
Then 60% would be 60 and 80% would be 80.
And there's an increase of 20 there.
20 is approximately 33% of 60. :)
