Question

Jar A contains 3 litres of juice, whereas Jar B contains 5 litres 250 ml of juice.
In jar C, both juices are combined, and one-third of the juice is withdrawn from the jar C. Calculate the amount of juice remaining in jar C.

• A. $3.3l$
• B. $2.4l$
• C. $7.2l$
• D. $5.5l$

Answer 1

The correct option is D $5.5l$

Volume of juice in jar A $=3l$
Volume of juice in jar B $=5l$ $250ml$

Let's convert ml into liter.
We know,
$1l=1000ml$
$\therefore 250ml=\frac{250}{1000}=0.25l$
Now,
$5l250ml=5l+0.25l=5.25l$
According to question,
Amount of juice in jar C initially = Amount of juice in jar A + Amount of juice in jar B
$=3l+5.25l$
$=8.25l$

Amount of juice taken out from jar C $=\frac{1}{3}$ of the amount of juice in jar C
Amount of juice remaining in jar C $=(1-\frac{1}{3})$ of the amount of juice in jar C
$=\frac{2}{3}$ of the amount juice in jar C
$=\frac{2}{3}\times 8.25=5.5l$
$(\because \text{Juice in jar C = 8.25 l})$

Hence, amount of juice remaining in jar C is $5.5l$.
