If DISTANCE is written as IDTUBECN and DOCUMENT is written as ODDVNTNE then how THURSDAY will be written?
Explanation
 DISTANCE = IDTUBECN and DOCUMENT = ODDVNTNE
 Here, in both the examples first two letters of the words are interchanged.
 Like, DI = ID and DO = OD
 Next three letters of the words are incremented by one position.
 Like, STA = TUB and CUM = DVN
 Last three letters of the words are written in the reverse order.
 Like, NCE = ECN and ENT = TNE
 We have to apply all these things to word THURSDAY.
 So, TH = HT
 Then URS = VST
 In last DAY = YAD
 So, THURSDAY will become HTVSTYAD.

Question
What minimum sampling frequency is required for 20 − 20 kHz analog signal? (2004)
Choices
Choice (4)  Response  

a.  44.1 kHz 

b.  20 kHz 

c.  40 kHz 

d.  20 Hz 

Answer
c.Explanation
According to Nyquist Criteria the sampling frequency should be greater or equal to two times the signal frequency to remove the effects of aliasing effect. Here, highest signal frequency component is 20 kHz. So, to receive the correct signal at the receiver end the sampling frequency should be at least twice of it. So, sampling frequency should be 40 kHz.

If length of rectangle of increases by 20 % and breadth decreases by 20 % then what will be the new area? (2004)
Explanation
 Area of rectangle = length breadth
 Let the length of rectangle be l and breath be b. Then area of rectangle will be = l b
 Now length of rectangle is increased by 20%. So, new length will be = l + 20 % of l
 = 1.2l
 Breadth is decreased by 20%. So, new breadth will be = b  20 % of b
 = 0.8b
 Now, new area will be =
 = 1.2 0.8
 = 0.96
 Here, = 0.96
