Explanation:
Let the total earnings of family is 100 for August
Zelensky earning for August will be 40%. i.e. 40
Rest of family income will be = 100 - 40 = 60
For September, it will be 40x0.8 = 32
% = 32 * 100 /(60+32)
= 34.7 %

Hi GmatNinja,
Can you please explain how did we arrive to 0.8 in the statement (0.4*0.8) mentioned in your video. I think its 1-0.2 but when do we apply this, only in case of decrease? Can you also give a similar example for percent increase as well?
Thanks in advance!!!
