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.
