    12 questions related to a passage (reading comprehension) 

    APTITUDE:
    1) My flight takes of at 2am from a place at 18N 10E and landed 10 Hrs later at a place with coordinates 36N70W. What is the local time when my plane landed?
    6:00 am b) 6:40am c) 7:40 d) 7:00 e) 8:00
    Sol) The destination place is 80 degree west to the starting place. Hence the time difference between these two places is 5 hour 20 min. (=24hr*80/360).

    2)) The size of the bucket is N kb. The bucket fills at the rate of 0.1 kb per millisecond. A programmer sends a program to receiver. There it waits for 10 milliseconds. And response will be back to programmer in 20 milliseconds. How much time the program takes to get a response back to the programmer, after it is sent? Please tell me the answer with explanation. Very urgent.
    Sol) see it doesn't matter that what the time is being taken to fill the bucket. after reaching program it waits there for 10ms and back to the programmer in 20 ms. then total time to get the response is 20ms +10 ms=30ms

    3) Three companies are working independently and receiving the savings 20%, 30%, 40%. If the companies work combinely, what will be their net savings?
    suppose total income is 100
    so amount x is getting is 80
    y is 70
    z =60
    total=210
    but total money is 300
    300-210=90
    so they are getting 90 rs less
    90 is 30% of 300 so they r getting 30% discount

    4)) 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: -1
    because g(2)=g(1)-g(0)=1+1=2
    g(3)=1
    g(4)=-1
    g(5)=-2
    g(6)=-1

    5)) what's the answer for that :
    A, B and C are 8 bit no's. They are as follows:
    A -> 1 1 0 0 0 1 0 1
    B -> 0 0 1 1 0 0 1 1
    C -> 0 0 1 1 1 0 1 0 ( - =minus, u=union)
    Find ((A - C) u B) =?
    To find A-C, We will find 2's compliment of C and them add it with A,
    That will give us (A-C)
    2's compliment of C=1's compliment of C+1
    =11000101+1=11000110
    A-C=11000101+11000110
    =10001001
    Now (A-C) U B is .OR. logic operation on (A-C) and B
    10001001 .OR . 00110011
    The answer is = 10111011,
    Whose decimal equivalent is 187.

    6)) In a two-dimensional array, X (9, 7), with each element occupying 4 bytes of memory, with the address of the first element X (1, 1) is 3000, find the address of X (8, 5).
    Sol) initial x (1,1) = 3000 u have to find from x(8,1)so u have x(1,1),x(1,2) ... x(7,7) = so u have totally 7 * 7 = 49 elements u need to find for x(8,5) ? here we have 5 elements each element have 4 bytes : (49 + 5 -1) * 4 = 212 -----( -1 is to deduct the 1 element ) 3000 + 212 = 3212

    7) In Madras, temperature at noon varies according to -t^2/2 + 8t + 3, where t is elapsed time. Find how much temperature more or less in 4pm to 9pm. Ans. At 9pm 7.5 more
    Sol) In equestion first put t=9,
    we will get 34.5...........................(1)
    now put t=4,
    we will get 27..............................(2)
    so ans=34.5-27
    =7.5

    8)) A person was fined for exceeding the speed limit by 10mph.another person was also fined for exceeding the same speed limit by twice the same if the second person was travelling at a speed of 35 mph. find the speed limit
    Sol) (x+10)=(x+35)/2
    solving the eqn we get x=15

    9))A work is done by the people in 24 min. One of them can do this work alone in 40 min. How much time required to do the same work for the second person
    Sol) Two people work together in 24 mins.
    So, their one day work is
    (1/A)+(1+B)=(1/24)
    One man can complete the work in 40mins
    one man's one day work (1/B)= (1/40)
    Now,
    (1/A)=(1/24)-(1/40)
    (1/A)=(1/60)
    So, A can complete the work in 60 mins

    10))One fast typist type some matter in 2hr and another slow typist type the same matter in 3hr. If both do combinely in how much time they will finish.
    Sol) Faster one can do 1/2 of work in one hourslower one can do 1/3 of work in one hour both they do (1/2+1/3=5/6) th work in one hour. so work will b finished in 6/5=1.2 hour i e 1 hour 12 min.

    11)A fisherman's day is rated as good if he catches 9 fishes, fair if 7 fishes and bad if 5 fishes. He catches 53 fishes in a week n had all good, fair n bad days in the week. So how many good, fair n bad days did the fisher man had in the week
    Ans:4 good, 1 fair n 2 bad days
    Sol) Go to river catch fish
    4*9=36
    7*1=7
    2*5=10
    36+7+10=53...
    take what is given 53
    good days means --- 9 fishes so 53/9=4(remainder=17) if u assume 5 then there is no chance for bad days.
    fair days means ----- 7 fishes so remaining 17 --- 17/7=1(remainder=10) if u assume 2 then there is no chance for bad days.
    bad days means -------5 fishes so remaining 10---10/5=2days.
    Ans: 4 good, 1 fair, 2bad. ==== total 7 days

    Sol. Remember that we have been asked to write to find address of last element not of first element. 3000+8*4+3*4+3(for last element) = 3047 

    27. My flight takes of at 2am from a place at 18N 10E and landed 8 Hrs later at a place with coordinates 36N 80W. What is the local time when my plane landed.
    Ans. Every 1 deg longitude is equal to 4 minutes . If west to east add time else subtract time) and measure the longitude form GMT do the difference between the longitude is 90 degree=90*4=360minutes=6 hours.

    CRITICAL REASONING
    there would be 3 passages and 4 questions each (total 12 quest)
    NOTE: go through GRE BARRON'S 12th edition i m giving some important passages as seen in fresherworld :- 

    Model test 1: Section5 - qns 1-4 (motorist), qns 13-16 (red and brown) 

    Section6 - qns 1-4 (conservative, democratic), qns 8-11 (latin, sanskrit), qns 12-18 (joe,larry,ned), qns 19-22 (a causes b) 

    Model test 2: Section1 - qns 19-22 (wallachia and rumelia) ---i got this qn, but the names were changed as london and paris , and a,b,c etc were changed as french, italian etc. 

    Section6 - qns 8-12 ( ashland , liverpool), qns 13-16 (spelunker) ---i got this qn, qns 17-22 (pesth) ---i got this one too 

    Model test 3: Section6 - qns 1-4 (all Gs are Hs) 

    Model test 4: Section5 - qns 8-11 (horizontal row), qns 19-22 (a,b,c cause d) 

    Section6 - qns 8-12 (spanish, italian), qns 13-16 (all As, Bs), qns 17-22 (progressive federal party) 

    Model test 5: Section3 - qns8-11 (museum), qns 19-22 (A is the father) 

    Section7- qns 1-5 (prahtu, brahtu), qns 21-25 (scurvy) 

    This passages are more than enough to clear critical reasoning, with out GRE barrons 12th edition it is difficult to clear the written test .
