Q:

In 1990 a person is 15 years old. In 2000 that same person is 5 years old. How can this be possible?

Answer

 It can be possible in only B.C. i.e, Before Christ. That was about 2000 years ago.


 Given, 


 In 1990 B.C = 2000 + 1990 = 3990 years ago, a person is 15 years Old  


=> In 1995 B.C = 2000 + 1995 = 3995 years ago, the same person will be 10 years Old 


Therefore, In 2000 B.C = 2000 + 2000 = 4000 years ago, the same person will be 5 years Old.

Q:

Pipe K fills a tank in 30 minutes. Pipe L can fill the same tank 5 times as fast as pipe K. If both the pipes were kept open when the tank is empty, how much time will it take for the tank to overflow ?

A) 3 minutes B) 2 minutes
C) 4 minutes D) 5 minutes
 
Answer & Explanation Answer: D) 5 minutes

Explanation:

Let the total capacity of tank be 90 liters.
Capacity of tank filled in 1 minute by K = 3 liters.
Capacity of tank filled in 1 minute by L = 15 liters.
Therefore, capacity of the tank filled by both K and L in 1 minute = 18 liters.
Hence, time taken by both the pipes to overflow the tank = 90/18 = 5 minutes.

Q:

How many 3-digit numbers can be formed from the digits 2, 3, 5, 6, 7 and 9 which are divisible by 5 and none of the digits is repeated ?

A) 15 B) 20
C) 5 D) 10
 
Answer & Explanation Answer: B) 20

Explanation:

Since each number to be divisible by 5, we must have 5 0r 0 at the units place. But in given digits we have only 5.

 

So, there is one way of doing it.

 

Tens place can be filled by any of the remaining 5 numbers.So, there are 5 ways of filling the tens place.

 

The hundreds place can now be filled by any of the remaining 4 digits. So, there are 4 ways of filling it.

 

Required number of numbers = (1 x 5 x 4) = 20.

Q:

Processor's speed of a computer is measured in

A) Hertz B) Baud
C) MIPS D) BPS
 
Answer & Explanation Answer: A) Hertz

Explanation:

CPU speed is the central factor in a computer's performance. And this CPU speed depends on the processor in the CPU chip. In a computer, clock speed refers to the number of pulses per second generated by an oscillator that sets the tempo for the processor. Clock speed is usually measured in Hertz (Hz).

 

But now-a-days, a pure processor's performance is measured in MIPS (Millions of Instructions Per Second). As here in the question, how a processor's speed is measured is asked and it is Hertz. 

 

Hence, Processor's speed of a computer is measured in Hertz(Hz) [MHz, GHz].
