Question

The weight of a gas cylinderr filled with gas is 32 kg 200 g .The weight of the gas contained in it is 17 kg 80 g ,find the weight of the empty cylinder

Answer 1

Answer:

it will be subtract because the question asked that what is the weight of an empty cylinder .

Answer 2

The weight of the empty cylinder is 15 kg 120 gm.

--------------------------------------------------------------------------------------------------

Let's understand a few concepts:

Conversion from gram to kilogram:

$\boxed{\bold{1 \:gram = \frac{1}{1000} \:kg = 0.001\:kg }}$

or

$\boxed{\bold{1 \:kg = 1000\:g }}$

----------------------------------------------------------------------------------------------------

Let's solve the given problem:

For easy calculation, we will convert the measurements to one single unit:

32 kg 200 g = 32 kg + (200 × 0.001) kg = 32 + 0.2 = 32.20 kg

17 kg 80 g = 17 kg + (80 × 0.001) kg = 17 + 0.8 = 17.08 kg

The weight of a gas cylinder filled with gas = 32.20 kg

The weight of the gas contained in it = 17.08 kg

Therefore,

The weight of the empty cylinder is,

= [Weight of a filled cylinder] - [Weight of the gas in the cylinder]

= 32.20 kg - 17.08 kg

= 15.12 kg

we will break down 15.12 kg into kg and g

= 15 kg + 0.12 kg

= 15 kg + (120 \times 0.001) kg

= 15 kg 120 g

Thus, the weight of the empty cylinder is 15 kg 120 g.
