# Number Operation:

1) Gita’s Weight Is 12 kg, and Her Brother Weighs Double Her. What Will Be Their Total Weight on the Moon?

The weight of Gita’s brother is
= (12 × 2) kg
= 24 kg
Their total weight is
= 12 kg + 24 kg
= 36 kg
Their total weight on the moon will be
= 36 kg ÷ 6
= 6 kg

2) The Teacher Asks Ram and Nisha to Calculate Their Total Weight on the Moon When Their Weight Is 10 kg and 8 kg, respectively.

Their total weight is
= 10 kg + 8 kg
= 18 kg
So, their total weight on the moon will be
= (18 ÷ 6) kg
= 3 kg

3) The Weight of a Basket of Apples Is 24 kg, and the Weight of a Cotton Bag is 18 kg. Find Their Weights on the Moon and Compare Which One Is Heavier There. Also, Find How Much Heavy It Is.

The weight of a basket of apples on the moon is
= (24kg ÷ 6)
= 4 kg
The weight of a bag of cotton on the moon is
= (18 kg ÷ 6)
= 3 kg
Hence, apple is heavier than cotton on the moon.
The weight difference is
= 4 kg – 3 kg
= 1 kg

4) The Weight of an Astronaut on the Moon Is 12 kg. Find the Weight of the Astronaut on the Earth.

The weight of the astronaut on earth is
= (12 × 6) kg
= 72 kg

5) The Weight of Any Object on Neptune Is 114 kg, While on Earth, the Weight of the Object Is 100 kg. Find the Difference in the Mass of the Object on the Different Planets.

Mass is constant for any object in any place.
The weight differs from one planet to another due to the change in
gravitational force. Hence, the difference in the mass is 0.
