Without formula general method...
If cp of article is 100
Getting 20% profit means, = 120 (SP)
Profit = 120-100 = 20
According to question calculate percentage of profit on its sp
= 20% Sp => (20/120)*100
= 16 2/3
Ans B
While calculating desired profit why you have taken C.P/S.P i.e ( x/5 X 5/6x) but the actual formula is (GAIN/C.P)*100 then it becomes
((6x/5-x)/x)*100 = ((x/5*1/x*100)) = 20.
