Are you preparing for an interview at CISCO? If so, you must be well-prepared for all types of aptitude questions that will be asked during the job interview. As you know, aptitude tests measure the capacity of candidates for logical thought, in-depth analysis, and problem-solving. They also assess the individual capacity for problem-solving, decision-making abilities, and numerical skills. Thus, you must be well-prepared with some fundamental aptitude questions and their answers to pass the job test. To help you with the test, here are some of the most common aptitude questions you’ll likely face in the CISCO job test.

1. A pipe can fill a tank in 3 hours. There are two outlet pipes from the tank which can empty it in 5 and 10 hours respectively. If all the three pipes are opened simultaneously, then the tank will be filled in -

• Net part filled in 1 hour

$=\frac{1}{3}-\left(\frac{1}{5}+\frac{1}{10}\right)$

$=\frac{1}{3}-\frac{3}{10}$

$=\frac{1}{30}$

• $\therefore$ The tank will be filled in 30 hours.

1. How much Simple Interest can a person get on Rs. 8,200 at 10.5% p.a. for a period of 2 years and 6 months?

• P=8200

N=2.5

R=10.5%

• I=$\frac{8200\times10.5\times2.5}{100}$

=$\frac{8200\times105\times25}{10000}$= 2152.5

1. A person purchases 10 apples for Rs.100 and sells 8 for Rs.100,then his gain percentage is?

• Profit % = $\left ( \frac{SP - CP}{CP}\right )\times 100$
• Profit % = $\frac{2}{8}\times 100$

= $\frac{100}{4}$ = 25%.

1. If Arun purchases 20 oranges for Rs.50 and sells 15 oranges for Rs.50,then his gain percentage is?

• Profit % = $\frac{SP - CP}{CP} \times 100$
• Profit % = $\frac{5}{15}\times 100$

= $\frac{100}{3}$

= 33.33%.

1. $a-\frac{1}{a} = 11, a^{2}+\frac{1}{a^{2}} = ?$
• If $x-\frac{1}{x} = a$ then,$x^{2}+\frac{1}{x^{2}} = a^{2}+2$
$a-\frac{1}{a} = 11, a^{2}+\frac{1}{a^{2}} = 11^2+2=123$
• We can find the same by using the equation,$(a-b)^{2}=a^{2}+b^{2}-2ab$
