Question

A bottle contains 920ml of mustard oil. The total quantity of oil contained in 25 such bottles, is.........
$\left( a \right)$ 23 liters
$\left( b \right)$ 25 liters
$\left( c \right)$ 24 liters
$\left( d \right)$ 22 liters

Answer 1

Hint: In this particular question use the concept that in 1 liter there are 1000 ml so the amount of mustard oil that holds 25 bottles is the multiplication of total number of bottles and the amount of mustard oil in one bottle, so use these concepts to reach the solution of the question.

Complete step by step answer:
Given data:
Amount of mustard oil in a bottle = 920 ml.
Now we have to find out the amount of mustard oil in 25 bottles.
As we all know that 1 liter = 1000 ml.
So 1ml = $\dfrac{1}{{1000}}$ liters.
Therefore, 920 ml = $\dfrac{{920}}{{1000}} = 0.92$ liters.
So in a bottle there is 0.92 liter mustard oil.
So in 25 bottles the amount of mustard oil in liters is the multiplication of the number of bottles and the amount of mustard oil in one bottle in liters.
So in 25 bottles the amount of mustard oil = 25 (0.92) = 23 liters.
So in 25 bottles there are 23 liters of mustard oil present.
So this is the required answer.

So, the correct answer is “Option A”.

Note: Whenever we face such types of questions the key concept we have to remember is that first convert the given ml into liters using unit conversion as above, then multiply this amount of liters by 25 as above and simplify we will get the required amount of mustard oil in liters in 25 bottles.
