Question 107

The given figure represents a weighing balance. The weights of some objects in the balance are given. Find the weight of each square and the circle.

Answer 1

From the given figure,

Consider only right hand side of balance, we get,
14 kg+weight of square = weight of circle+4 kg

Weight of square = Weight of circle-10 kg...(1)

Now Consider whole balance
20 kg + 20 kg = weight of square +14 kg+weight of circle+4 kg
Weight of circle + weight of square = 22 kg...(2)
From Equation (1) put value of Weight of Square in Equation (2)
Weight of circle + weight of circle - 10 kg=22 kg
2[weight of circle]=32kg
Weight of circle = 16 kg
Put value of weight of circle in equation (1)
weight of square + 10 kg=16 kg
Weight of square =6 kg
