Read Solution (Total 3)
-
- In the initial case say S.P be x r.s. than profit is 20%
sp=(100+profit/100)*cp
100x=120cp
cp=5x/6 --------------------------------eq 1
now sp is doubled say 2x
2x=(100+p/100)*cp
2x=(100+p/100)*5x/6
solving we have p=140 - 7 years agoHelpfull: Yes(0) No(0)
- Let the C.P. = x,
Then S.P. = (120/100)x = 6x/5
New S.P. = 2(6x/5) = 12x/5
Profit = 12x/5 - x = 7x/5
Profit% = (Profit/C.P.) * 100
(7x/5) * (1/x) * 100 = 140 %
so the option is d 140% - 7 years agoHelpfull: Yes(0) No(0)
- Let the C.P. = x,
Then S.P. = (120/100)x = 6x/5
New S.P. = 2(6x/5) = 12x/5
Profit = 12x/5 - x = 7x/5
Profit% = (Profit/C.P.) * 100
=> (7x/5) * (1/x) * 100 = 140 % - 6 years agoHelpfull: Yes(0) No(0)
