Answer» Correct Answer - D Marked price = Rs. 480 Selling price after 10% discount (10% क) `=Rs. 480xx(90)/(100)=Rs. 432` Cost price `=432xx(100)/(100+8%)=432xx(100)/(108)` Rs. 400 If no discount then selling price =Marked price = Rs. 480 gain percent `=(480-400)/(400)xx100=(80)/(400)=20%` Alternate `therefore (100-D%)/(100+P%)=(CP)/(MP)` `(CP)/(MP)=(100-10)/(100+8)=(90)/(108)=(5)/(6)` If no discount then M.P =S.P ` therefore` CP=5, S.P=6 Gain% `=(6-5)/(5)xx100` `=(1)/(5)xx100=20%` |
