A) SMTP B) HTTP C) ARP D) SAP E)

3. Pick the odd one out:
A) DB2 B) ORACLE C) WAP D) ARP E)
(I might have interchanged some choices for Qs 2 & 3. Please check.)

Ans: A (since sum of the angles in a triangle = 180o.)

5. The following is a planar cube (E, V, F):
A) (12, 8, 6) B) (12, 6, 8) C) (6, 6, 8) D) (6, 8, 6)

A) 61 B) 63 C) 65 D) 67 E) 69

7. Calc. A-(B C) and represent the resulting 8-bit word in decimal form.
A 0 0 1 1 0 0 1 1
B 0 1 0 1 0 1 0 1
C 0 0 0 0 1 1 1 1
A-(B C)
(I might have interchanged the values of A, B & C but still try this.)

8. Fit a suitable curve with the given data.
x y
1000 3
… …
… …
… …
A) y = log x B) y = log 10x C) y = -10log x D) y = ex

B B G M P Q B G S K O B G A S B B G D E F B G S T I
Ans: 4 (Another Q on the same logic was also asked.)

10. M(373,5) + R(3.4) + T(7.7) - R(5.8) = ___
M - Modulo R - Round-off T - Truncate
Ans: 3 + 3 + 7 - 6 = 7
(In the above, first term means the remainder obtained after dividing 373 by 5.)

11. Match the following:
A) Female - Girl i) A type of
B) Bug - Reptile ii) A superset of
C) Beagle - Dog iii) A part of
D) Piston - Engine iv) Not a part of

13. 5 7 11 ? 25
Ans: 17

14. A, B & C can do a piece of work in 8 days. A alone can do it in 12 days and B alone can do it 16 days. Then C alone can do it in ___.

15. The line equation of the following curve is

A) y = ex B) y = tan x C) y = cos x D) x + y = 0
Ans: D (For some others, tan x and cos x curves were asked.)

16. A & B can do a piece of work in 12 days. A is capable of doing twice the work as B. In how many days A alone can complete the work?

17. If the first/second, third/fourth, fifth/sixth etc. letters of the word PSYCHIATRIST are interchanged, then the letter which is 8th from right is I .

18. If DCPRY is coded as CBOQX then SPEND can be coded as RODMC.

19. The following is not a triangle:
A) (2,3,4) B) (3,4,5) C) (5,5,5) D) (1,3,5)
Ans: D (Clue: Sum of any two sides should be greater than the third side.)

20. Temperature in Chennai is measured since 12 noon is given by (t2/9) + 4t + 16. Then the difference in temperatures between 4 pm and 9 pm is ___. (I don't remember the question but can only outline it.)
