The correct option is C 2847%
Given the original Marked price = Rs18,000
After 30 % discount, the shopkeeper buys it for (18000)−30100×18,000=Rs12,600
Total CP which he bears with the overheads is Rs12,600+Rs950+Rs450=Rs14,000
And if Selling Price =Rs18,000 (that is the marked price ),
then,
Profit % =S.P−C.P.C.P.×100=18,000−14,00014,000×100=27×100=2847 %
