Question

$\text{A vendor delivers}3\frac{2}{5}\text{L of juice}$ to a house. If he delivers juice to 4 houses, of juice has been delivered altogether.

• A. $12\frac{2}{5}L$
• B. $11\frac{1}{5}L$
• C. $13\frac{3}{5}L$
• D. $15\frac{4}{5}L$

Answer 1

The correct option is C $13\frac{3}{5}L$

$\text{Amount of juice delivered by the vendor}$
$\text{to 1 house =}3\frac{2}{5}$.

$\text{∴ Amount of juice delivered by the vendor}$
$\text{to 4 houses =}4\times 3\frac{2}{5}$

Now, the result can be expressed as:


$4\times 3\frac{2}{5}=(4\times 3)+4\times \frac{2}{5}$

$=12+\frac{4\times 2}{5}$

$=12+\frac{8}{5}$

$(Now,8=5+3)$

$=12+\frac{5}{5}+\frac{3}{5}$

$=12+1+\frac{3}{5}$

$=13\frac{3}{5}$

$\text{Hence, the vendor delivered}13\frac{3}{5}L$
$\text{of juice to 4 houses altogether}$.
