FLOW CHART:

1) Some flow chart is given. Five question on this flow chart.

i. Whether i will take the value 0
ii. Find value of i
iii. Find value of a
iv. Find value of j

Answers:
i. Yes
ii. -4
iii. 13
iv. 29

2) One more flow chart. Five questions

i. s value at 6th iteration
ii. value f3 when n=6
iii. f3 doesn’t take which value
iv. When s=57 what is the value of f3
v. What is the value n when program terminates.

Answer
i. 31
ii. 34
iii. 9
iv. 89
v. 11

Formulae involved in the flow chart: 
S = N2 - ( N – 1)
F3 = F1 + F2
F1 = F2
F2 = F3


mug this flow chart.. same flow chart came for us..it is very difficult to remember the ques.. i am sorry that i cudnt able to reproduce.. for the 3rd Section i remember few que: 

Section 3: 1- problem on tower of hanoi--ans 7
2 problem on fig. find the shaded area, square of size 14cm.. ans: 42 
3. problem on symmetric fig ;; ans less than the 1172(check) . 
4. few questions on blood relationship.. (refer r.s. agrawal reasoning) 
sample ques..man looking at photo tells that " the daughter of this person is the only son etc..." try to familiar on this ..
5 . again ques on relationship..; 6 persons are there A, B, C, D, E, F. 
i) how many male: ans -4
ii)how many female- ans 2
iii) how D related to A; - similar ques ..easy ..
6)u have the series of letters..need to find the odd one out.. 
tips: u identify the pattern all the choices follow the pattern except one..

eg: given words are say ..ABCD , JKLM, OPQR, UVWX, EGHI 
in this the last set do not follow the pattern.. 
in case of ABCD- all are continious. 
JKLM , OPQR, UVWX..follow same all are continious .. 
If u see the EGHI – this is not continious as EFGH shud me there..got it …

U have 4 ques on this..easy one..

6) u have to fill the missing letter in the series.. little bit tough.. 4 ques..but easy..
7) u have 3 figure –based on the figures ques asked.. easy one.. 
eg: Fig Triangle means Strong
Fig Square means Tall 
Fig Circle means Fair.
Ques asked is find the number that represents Strong Tall and Fair persons.. easy one ..
So u have 3 ques on this pattern.. 

8) u have ques on flow chart..easy..very simple..


NOTE: they r looking for the toppers ..so if u r the topper than no probs. Mostly CGPA of 8 + is they expect. To shortlist.
