Hi Scott or Karishma,
I don’t understand the last step. Why do we need to divide 6 over 25x100?
Why isn’t the answer 6%? The question asks “what percentage of family time does he have to reduce?” He only spent 19% of family time so he had to reduce his time by 6%.
Can you please help me understand where I’m wrong? Thank you!

Say you scored 50% in a certain exam last year. This year you scored 40%. So your score went down by 10 percentage points.
But if you scored 50 last year and only 40 this year, the percentage decrease in your score is (10/50)*100 = 20%.
Similarly,
The family time was 25%. Now the family point is 19%. That is a drop of 6 percentage POINTS.
But he was spending 25 hrs with the family before. Now he is spending 19 hrs. So he had to reduce his family time by 6 hrs for 25 hrs he was spending before. What is this in percentage terms?
(6/25)*100 = 24%
