(I) Selling price of camera 'C' is Rs. 38,400. (II) Discount offered on buying camera 'D' is 20%. (III) Profit earned on selling camera 'D' is more than that on selling camera 'C'.Solution
ATQ, Marked price of camera 'C' = 160% of 40,000 = (1.6) x 40,000 = Rs. 64,000 Selling price of camera 'C' = 65% of 64,000 = (0.65) x 64,000 = Rs. 41,600 Profit earned on camera 'C' = Rs. 41,600 - Rs. 40,000 = Rs. 1,600 Marked price of camera 'D' = 180% of 50,000 = (1.8) x 50,000 = Rs. 90,000 Selling price of camera 'D' = 130% of 50,000 = (1.3) x 50,000 = Rs. 65,000 Discount offered on camera 'D' = (25,000/90,000) x 100 = 27.78% Statement (I) is false (the selling price of camera 'C' is Rs. 41,600, not Rs. 38,400). Statement (II) is false (the discount on camera 'D' is 27.78%, not 20%). Statement (III) is true (Rs. 15,000 profit on camera 'D' is more than Rs. 1,600 on camera 'C').
