Question

The solution in a jar with capacity of 2,850 pints is completely filled with mixtures of three oils. Two of the oils used are 440 pints and 310 pints respectively .
What is the quantity of the third oil used ?

• A. 2,100 pt
• B. 2,310 pt
• C. 2,010 pt
• D. 2,250 pt

Answer 1

The correct option is A 2,100 pt

$\text{Amount of oil in the jar = 2,850 pt}$

$\text{Amount of first oil in the jar = 440 pt}$
$\text{Amount of second oil in the jar = 310 pt}$

$\text{Total amount of both the oils}$ $\text{= 440 pt + 310 pt = 750 pt}$


To calculate the amount of third oil in the jar, we will subtract the amount of two oils in the jar from the total quantity of oil in the jar.


$\text{Hence, the quantity of the third oil is}$ $\text{2,100 pt.}$
