Question

The weight of a fuel pump is 3 kg 150 g. If the pump is made of 21 identical parts, the weight of each part in grams will be ____.

• A. 140 g
• B. 150 g
• C. 160 g
• D. 170 g

Answer 1

The correct option is B 150 g

You know,
1 kg = 1000 gm.


So, 3 kg will be:
$=3\times 1000=3000$ g.

Weight of the pump = 3kg 150g.
Converting the entire weight into grams,
$3kg150g=3000gm+150g=3150g.$

Now, the pump is made of 21 identical parts.

So, the weight of each part in grams will be equal to:
$3150÷21$.

Calculating $3150÷21$ by box method of divsion,


Adding the partial quotients, the final quotient as:
$100+40+10=150$.

Hence, the weight of each part of the pump will be 150 g.
