The weight of toy car = 122 g
2 toy cars are placed on one side of the weighing balance.
Weight of 2 toy cars = 2 × 122 g = 244 g
Weight of toy tractor = 236 g
So, weight of two toy cars is more than the weight of one toy tractor.
So, the pan which has two toy cars will move down and pan with toy tractor will move up in the weighing balance.
