Answer:
The given details are total weight of three boxes is 60 ½ kg = 121/2 kg Let the weight of box A be x kg Weight of box B be x + 7/2 kg Weight of box C be x + 7/2 + 16/3 kg So, x + x + 7/2 + x + 77/2 + 16/3 = 121/2 3x = 121/2 – 7/2 – 7/2 – 16/3 By taking LCM for 2 and 3 is 6 3x = (363 – 21 – 21 – 32)/6 3x = 289/6 x = 289/18 ∴ The weight of box A is 289/18 kg.Read more on Sarthaks.com - https://www.sarthaks.com/665597/ravish-has-three-boxes-whose-total-weight-2kg-weighs3-2kg-more-than-weighs5-more-than
