Question : 7

Total: 40

A bag of rice weighs 2 kg . If the empty bag weights 150 g , find the weight of the rice.

[1\,\text{kg}=1{,}000\,\text{g}

$0.175\,\text{kg}$
$0.185\,\text{kg}$
$1.850\,\text{kg}$
$1.750\,\text{kg}$

Solution:

Concept:

Subtract the weight of the empty bag from the total weight of the bag of rice.

Explanation:

First, convert

2\,\text{kg}

to grams:

2\,\text{kg} = 2 \times 1000\,\text{g} = 2000\,\text{g}

Weight of rice = total weight − empty bag weight

Weight of rice

= 2000\,\text{g} - 150\,\text{g} = 1850\,\text{g}

Convert

1850\,\text{g}

back to kilograms:

1850\,\text{g} = \frac{1850}{1000}\,\text{kg} = 1.85\,\text{kg}

Since

1.85\,\text{kg} = 1.850\,\text{kg}

, the correct option is C.

Answer:

C.

1.850\,\text{kg}
