1.Which shape will be obtained by using the following values for X and Y
 

      X     0             10      100    1000  9999 
 

      Y   0.00001     1.02   1.72   3.00   4.72
 

    Ans: Y= log10(X)
 

2.What is the value of the following expression    M(373,5)+T(7.7)+R(4.4)-T(3.6)
 

      Where M- MODULAS R- ROUNDOFF T- TRUNCATE    (Ans: 11)       Sol: 3 + 7+ 4 - 3 ==11

3 What is the value of the expression         % # % (6) + # % # (6)
 

          Where % means DOUBLING and # means RECIPROCAL        
 

4 Match the following (this type of question but not same)
 

                   A                                                       B
 

          1. Mammal, cow                        --->       a.   A type of
           2. Snake   reptile                        --->       b.   A part of
           3. Roof - Building                       --->       c.   Not a type of
           4. Mushroom - Vegetables         --->       d.   A superset of
 

            (Ans: 1-d, 2-c, 3-b, 4-a)
 

5.If G(0) = -1 G(1)= 1 and G(N)=G(N-1) - G(N-2) then what is the value  of G(6)?(Ans: -3)   
 

 Sol: g(2)=g(1)-g(0) ==1-(-1)=2, similarly g(3),…g(6);
 

6.   If  A=     0        0        0        0        1        1        1        1

          B=     0        0        1        1        0        0        1        1
 

          C=     0        1        0        1        0        1        0        1
 

Then find the value of [A U C] U B and express it in decimal.  

7.If A, B, C are the mechanisms used separately to reduce the wastage of fuel by 30%, 40%, 10%.What will be the fuel economy if they were used combine?
 

1.68.4          2.62.2         3.58         4.27              (Ans: 62.2)                                          

  sol:  (70/100)*(60/100)*(90/100)*100=37.8   Eco = (100-37.8) =62.2

8. In Madras , temperature at noon varies according to t^2/2 + 4t + 12 (Read is as: t square /2 + 4t +12), where t is elapsed time. Find how much percentage of temperature is increased (or decreased) between 5pm and 8pm. (HINT: substitute&subtact values from 5 to 8)
 

9 The size of a program is N. And the memory occupied by the program is given byM = square root of 100N. If the size of the program is increased by 1% then how much more memory is required now?
 

          a) 1.0%        b) 2.6%                 c) 0.5%       d)1.4%                  e)2.7%   ans .5%

10 A power unit is there by the bank of a river of 900 meters. A cable is made from power unit to power a plant opposite to that of the river of 2000mts. The cost of the cable below water is Rs. 5/- per meter and cost of cable on the bank is Rs. 4/- per meter. Then find out the amount to be invested to connect those two stations. (Ans8500)
 

11 A sequence of letters is given. We’ve to find out how many V’s are there under the condition that, S should be followed by V and should not be followed by F……
 

V,S,F,T,W,E,L,B,V,S,L,L,K,S,M,S,V,F,L,S,D,I,……… Like that.
 

12 In a two-dimensional array, X (7, 9), with each element occupying 8 bytes of memory, with the address of the first element X (1, 1)=3000; find the starting address of  the element at X (5,8).  (Ans: 3172)
 

Sol: (4 X 9) + 7 = 43 X 4= 172 à 3000+172 == 3172 ( i.e completely 4 rows r filled , in fifth row up 7th cell is filled next cell is required address )
 

13 In the word ORGANISATIONAL, if the first and second, third and forth, fifth and sixth, etc words are interchanged, what would be the 12th letter from right?    (Ans: ‘A’)
 

14 A Flight takes off at 4 A.M from North-East direction and travels for 7 hours to reach the destination in the North-West direction. Some latitude and longitude of source and destination given. Find the local arrival time of destination? (I don’t know how to find it)

15 Four 2X2 matrices were given. We’ve to find out which of them is a singular matrix? (Hint: try for which matrix det (A) becomes zero (ad - bc).

16 (Momentum*Velocity)/(Acceleration * distance)
 

          a) Newton     b) Mass                 c) Force
