Question

If $\frac{3}{4}th$ of a carton with oranges weighs 3 kilograms and 225 grams, what will the weight of the carton be when it is completely filled with oranges (in kilograms)?

• A. $5\frac{7}{10}kg$
• B. $3\frac{3}{10}kg$
• C. $4\frac{3}{10}kg$
• D. $4\frac{2}{10}kg$

Answer 1

The correct option is C $4\frac{3}{10}kg$

1 kg = 1000 g
3 kg = 3000 g

$3kg+225g=(3000+225)g=3225g$

We need to find the weight of the carton completely filled with oranges.

$\frac{3}{4}$th of the carton with oranges weighs 3225 g.

$\frac{1}{4}$th of the carton with oranges weighs $=\frac{3225}{3}=1075g$

Weight of the carton completely filled with oranges $=3225+1075$

$=4300g$

$=\frac{4300}{1000}kg$

$=\frac{43}{10}kg$

$=4\frac{3}{10}kg$
