Solution

Let M.P. = Rs. X, Discount = 20%ofx=Rs.x5
New M.P. after discount = Rs.xRs.x5=Rs.4x5
Again discount = 5% of Rs.4x5=Rs.x25
Changed M.P. after 2nd discount = Rs.4x5Rs.x25=Rs.19x25
Now, 2298.24=Rs.19x25+8% of Rs.19x25
2298.24=Rs.19x25+8100×19x25
=19x25+38x625
=475x+38x625
x=2298.24×625)513
x=Rs.2800
M.P. = Rs. 2800
