Question

A tank is attached by 8 taps some of which are
outlet some are inlet. Efficiency of all outlet
pipe and inlet pipes are same. Time taken by
an outlet pipe to empty the tank is double of
the time taken by the pipes (8 pipes) to fill the
tank. How many pipes are outlet?
A- 4
B-3
C-1
D-2​

A ) 4

Answer 2

Answer:

The number of outlet pipes is 4. So the correct option for this question is A- 4.

Step-by-step explanation:

If there are "n" inlet pipes, then "8 - n" output pipes are required.

∴ (8 - n)$\frac{1}{6}$ - n × $\frac{1}{8}$ = $\frac{1}{6}$ ⇒ n

n = 4

Alternatively:

(8 - n)16.66 - n × 12.5 = 16.66

n = $\frac{116.66}{29.16}$

n = $\frac{700}{175}$

n = 4

The above solution is based on applied mathematics analysis.

Applying mathematics to issues that arise in a variety of fields, such as science, engineering, or other fields, and/or developing new or improved approaches to tackle issues as they arise are both parts of applied mathematics. The use of mathematical techniques in a variety of disciplines, including physics, engineering, medicine, biology, finance, business, computer science, and industry, is known as applied mathematics. As a result, applied mathematics combines specific expertise with mathematical science. A major in applied math places a lot of emphasis on developing students' computational, communication, and mathematical abilities.

Thus, the study of applied mathematics links mathematical ideas and methods to numerous branches of science and engineering.
