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In jar C, both juices are combined, and one-third of the juice is withdrawn from the jar C. Calculate the amount of juice remaining in jar C.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. 5 l
• B. 5.1 l
• C. 5.5 ml
• D. 5.5 l

Answer 1

The correct option is D 5.5 l

Volume of juice in jar A $=3l$
Volume of juice in jar B $=5l$ $250ml$
Convert ml into liter
We know,
$1l=1000ml$
$\therefore 250ml=\frac{250}{1000}=0.25$ l
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
$=\frac{2}{3}\times 8.25=5.5l(\because \text{juice in jar C = 8.25l})$
Hence, amount of juice remaining in jar C is 5.5 l.
