I have been looking into the recordings of Greg mat and I can’t figure out why the %increase is 100?

This is the question :

I thought the answer is 300%. Let me know if I am wrong or am I missing something here?

Q1 would be:

if you assume unknown percentage as p

30 = 15 X p/100

30*100 = 15 X p

3000 /15 = p

200 = p

Thus, p=200%

Q2 would be:

Percentage Increase =( (Big Number−Small Number)/(Small Number )) * 100 percent

=( (30-15)/15) * 100 percent

= (15/15) * 100 percent

= 1 * 100 percent

= 100 percent

I hope this helps @iam_venkat03

hi @user514

In Q2, the smaller number is -15 and not 15.

So, doesn’t (Big no - small no) became (30-(-15)) = (45/15)*100 = 300%?

it is just hyphen it is there in first question too @iam_venkat03

Yeah. But even if it’s -30 in the Q1, its still 200%. But if I consider -15 or 15 in the Q2 the whole answer changes.
