Question

Ravish has three boxes whose total weight is 60 Kg Box B weighs 3 kg more than box A and box C weighs 5 13 kg more than box B Find the weight of box A

Accepted 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
