उत्तर

Selling price (SP) = Rs 9250

Discount % = `7 1/2% = 15/2%`

Let marked price be Rs x.

∴ Selling price = `"Marked price" - ("Discount" %)/100 xx "MP"`

⇒ `9250 = x - 15/(2 xx 100) xx x`

⇒ `9250 = (200x - 15x)/200`

⇒ `9250 = (185x)/200`

⇒ `x = (9250 xx 200)/185`  ...[By cross-multiplication]

⇒ `x = 1550000/185 = Rs 10000`

Hence, the market price = Rs 10000.
