The answer to this question will be a single discount of 40.15%.
We can get this value using net increase or decrease.
Discount is decreased therefore we use the formula-: ( -a-b)+(ab/100).
(-30-10)+(30*10/100).
=-40+3.
= -37.
Again we'll use this same formula.
(-a-b)+(ab/100).
=(-37-5)+(37*5/100).
=-42+1.85.
= -40.15
It is in negative cause discount is decreased.
Hope it helps.
