Solution
Let M.P. = Rs. X, Discount = 20%ofx=Rs.x5 New M.P. after discount = Rs.x−Rs.x5=Rs.4x5 Again discount = 5% of Rs.4x5=Rs.x25 Changed M.P. after 2nd discount = Rs.4x5−Rs.x25=Rs.19x25 Now, 2298.24=Rs.19x25+8%ofRs.19x25 2298.24=Rs.19x25+8100×19x25 =19x25+38x625 =475x+38x625 x=2298.24×625)513 x=Rs.2800 M.P. = Rs. 2800
