Let the original price of the mobile phone be Rs. ‘100x’ So, new price of the mobile phone = 100x × 1.25 × 0.75 = Rs. ‘93.75x’ So, 93.75x = 675 So, x = 7.2 So, original price of the mobile phone = 100 × 7.2 = Rs. 720 Alternate solution: Original cost of the mobile phone = 675 ÷ 0.75 ÷ 1.25 = Rs.720
