Question : Pipes A and B can fill a tank in 12 minutes and 15 minutes, respectively. The tank when full can be emptied by pipe C in $x$ minutes. When all three pipes are opened simultaneously, the tank is full in 10 minutes. The value of $x$ is:

Option 1: 18

Option 2: 15

Option 3: 20

Option 4: 24

Team Careers360 22nd Jan, 2024

Correct Answer: 20


Solution : Pipe A can do 1 unit work = $\frac{1}{12}$ minutes                                   
Pipe B can do 1 unit work = $\frac{1}{15}$ minutes 
Pipe C can do 1 unit work = $-\frac{1}{x}$ minutes
Together they can fill the tank = $\frac{1}{10}$ minutes
Total work = Efficiency × days
$⇒\frac{1}{\text{total days}} = \frac{1}{\text{A}} + \frac{1}{\text{B}} - \frac{1}{\text{C}}$
$⇒\frac{1}{10} = \frac{1}{12} + \frac{1}{15} - \frac{1}{x}$
$⇒\frac{1}{x} = \frac{1}{12} + \frac{1}{15} - \frac{1}{10}$
$⇒\frac{1}{x} = \frac{(5 + 4 - 6)}{60}$
$⇒\frac{1}{x} = \frac{3}{60}$
$\therefore x = 20$
Hence, the correct answer is 20.

Do I need to have maths in 12th to study psychology ?

shivamtrivedi0005 15th Oct, 2023

Hello aspirant,

One area of the social sciences is psychology. Therefore, you are not required to take Mathematics in your 12th grade curriculum if you wish to pursue Psychology as a subject for your Bachelor's degree. Biology, Chemistry, and Physics should have been studied by you. The requirements for eligibility vary depending on the college you wish to apply to. However, mathematics is not usually a required subject.

Thank you

Hope it helps you.
