You need to know the actual cost on which you will calculate any profit/loss
Loss = Cost - Sale
.......cost is the base here, put values
20% of cost = Cost - 200
or
200 = 100% C - 20% cost
200 = 80% C
so
C = 250
now 10 % gain/profit on cost
250*10% = 25
so it must be sold in 250+25 = 275
Ans. D) 275
