Answer 2

Answer:

Step-by-step explanation:

1 - Whenever there's an 'of' something, or some value, in percentage based questions, use an x(multiplication symbol). Don't ask why, remember Nike's tagline.

2 - Notice the question has 'of a number,' let's use 'N' to denote it. You can use any letter. All we need to do now is to show all of this in a math-y sort of way  :-

5/12 x 2/5 x 20% x N

3 - Now that you know why the vast majority of human population hates Math, you remember from the question that this whole thing results in 252. So you show it in your math-y way, AGAIN :-

5/12 x 2/5 x 20% x N = 252

4 - Now that we have our magical equation, we solve it!

5 cuts 5, 2 cuts 12 with a 6, 20% becomes 1/5, and after that bloody massacre, we have  :-

1/6 x 1/5 x N = 252

(we continue solving it)

=>1/30 x N = 252

=> N = 252 x 30/1

=> N = 7560
