उत्तर

Case 1: Profit = Selling price (S.P) – Cost price (C.P)

Case 2: Loss = Cost price (C.P) – Selling price (S.P)

Given that profit of case 1 = loss of case 2

∴ P = 810 – C.P

L = C.P – 530

Since profit (P) = loss (L)

810 – C.P = C.P – 530

∴ 2C.P = 810 + 530 = 1340 

⇒ C.P = `1340/2`

∴ C.P = 670
