S. P. of the article = Rs. 1440

Let marked price = Rs. 100 x

Discount = 20%

∴ S. P. = (100x (100 – 20))/100 = 80x

According to statement, 80x = 1440

X = 1440/80 ⇒ x = 18

∴ x = 18

∴ Marked price = 100x = 100 × 18 = Rs. 1800

S.P. = Rs. 1440

Profit = 25%

∴ C. P. = (100 × S.P.)/ (100 + 25) = (100 × 1440)/125 = (4/5) × 1440

= 4 × 288 = Rs. 1152
