Abox with 3 metal balls weighs 1840 kg.
each metal ball weighs thrice as heavy as the box.
how much does a box with 1 metal ball weigh?

736 Kg

Step-by-step explanation:

Let the weight of the box be x, then

the weight of each ball = 3x

Sum the weight of the box and 3 balls and equate to 1840, that is

x + 3x + 3x + 3x = 1840

10x = 1840 ( divide both sides by 10 )

x = 184

The weight of the box = 184 Kg and the weight of 1 ball = 3 × 184 = 552 Kg

The weight of the box and 1 ball = 184 + 552 = 736 Kg
