Let the CP of the article be 100a. Now, SP for 1st case = 100a - 100a × 10(1/2) % = 89.5a SP for 2nd case = 100a + 100a × 11(3/5) % = 111.6a According to the question, 111.6a - 89.5a = 375.70 22.1a = 375.70 a = 375.70/22.1 a = 17 So, cost price = 100 × 17 Rs. 1700 ∴ The cost price (in Rs.) of the article is 1700. Second method- Given – loss% = 10(1/2) and profit% 11(3/5) Increased selling price = 375.70 Let cost price =100 ATQ- 10(1/2) +11(3/5) = 375.70 21/2 + 58/5 = 375.70 (105 + 116) /10 =375.70 1 =3757/221 = 17 Then CP = 100×17 = 1700 Rs
