On selling an article for ₹115, the gain is 20% more than the loss incurred on selling it for ₹104. If the article is sold for ₹130.80, then the profit percentage is:

20

\(\frac{P}{L}\)  = \(\frac{6}{5}\)

In both cases Cost price will be same.

⇒ S.P₁ - P = S.P₂ + L

⇒ 115 - 6n = 104 + 5n

⇒ 6n + 5n = 115 - 104

⇒ 11n = 11

⇒ n = 1

⇒ 115 - 6 = 109 = C.P.

New SP of the article = Rs. 130.80

P% = \(\frac{(130 – 109) × 100}{109}\) = 20%
