• A. 2269 kg
• B. 42.686 kg
• C. 6814 kg
• D. 4.268 kg

Answer 1

The correct option is B

42.686 kg

We know that $1\text{kg}=1000\text{g}.$
$\therefore 2314\text{g}=\frac{2314}{1000}\text{kg}=2.314\text{kg}$

We need to subtract 2.314 kg from 45 kg.

We use equivalent decimal of 45 with three decimal places as 45.000 and equivalent decimal of 2.314 with three decimal places as 02.314 .

$45.000-\underset{–}{02.314}42.686$

$\therefore$ We get 42.686 Kg, on subtracting 2314 g from 45 kg.
