Formula: 1 Mark
Steps: 2 Marks
Answer: 1 Mark
Let M.P. be Rs x, Discount =20% of Rs x=Rsx5
New M. P. after discount =Rs x−Rsx5=Rs4x5
Again discount =5% of Rs4x5=Rsx25
Changed M.P. after 2nd discount =Rs4x5−Rsx25=Rs19x25
Now, 2298.24=19x25+8% of 19x25
⇒2298.24=19x25+8100×19x25
=19x25+38x625=475x+38x625
⇒x=2298.24×625513
⇒x=Rs 2800
∴ M.P. Rs 2800
