      Solution

      ATQ, Marked price of mobile 'M' = 145% of 22,000 = (1.45) x 22,000 = Rs. 31,900 Selling price of mobile 'M' = 70% of 31,900 = (0.7) x 31,900 = Rs. 22,330 Profit earned on mobile 'M' = Rs. 22,330 - Rs. 22,000 = Rs. 330 Marked price of mobile 'N' = 155% of 28,000 = (1.55) x 28,000 = Rs. 43,400 Selling price of mobile 'N' = 118% of 28,000 = (1.18) x 28,000 = Rs. 33,040 Discount offered on mobile 'N' = (10,360/43,400) x 100 = 23.87% Statement (I) is false (the selling price of mobile 'M' is Rs. 22,330, not Rs. 23,100). Statement (II) is false (the discount on mobile 'N' is 23.87%, not 12%). Statement (III) is true (Rs. 5,040 profit on mobile 'N' is more than Rs. 330 on mobile 'M').
