## rvc one year ago If aN implies S eF implies I gH implies M then nS implies ?

1. rvc

The options are : 1)T 2)A 3)L 4)K

2. rvc

@ikram002p @Loser66

3. rvc

what is the logic?

4. Loser66

I am trying but not find out yet. ha!!

5. Loser66

I don't know!! I am sorry.

6. rvc

okay thanks for trying @Loser66

7. princeharryyy

eF implies I or L @rvc

8. rvc

I

9. princeharryyy

ok! let me ntry n find the connection.

10. anonymous

I think its K... I have a weird reason... is the answer known to you @rvc?

11. rvc

no i dont know the ans

12. mathmath333

What is the source of the question is it related to mathamatics .

13. rvc

yeah

14. Loser66

@mathmath333 it's called encryption maths

15. mathmath333

ok i see @Loser66

16. freckles

hey @rvc can I asked where this question came from?

17. rvc

This question is from NET Exam

18. freckles

Can I find that exam on the internet?

19. rvc

i dont know you may please try :)

20. freckles

so loser said it had something to do with encryption is there anything else you can tell me about this problem? Like there are all kinds of encryption systems... I guess this is a mathematics Net exam?

21. rvc

22. Empty

Since aN implies S then backwards we have while changing the case to match: nS implies A. A is an answer choice, but this is a super weak reason for this to be the answer haha.

23. freckles

if nothing else was given how did loser know this had something to do with encryption?

all I did 1-26 for capital letters and 27-52 for lower case letters didn't find a pattern

26. rvc

:/

27. dan815

you..

28. dan815

why are u still here, family reunion boy

29. Empty

I was considering the rotational and reflectional symmetries of the letters and also considering their placement on a keyboard to see if there was a relationship, also vowels and consonants, still nothing. I don't leave until tomorrow dan lol

30. Empty

The only patterns I'm seeing are: lower case, upper case implies upper case and the answer choices spell out TALK.

31. Empty

Honestly if someone can legit figure this out in a way that's reasonable, I'll give you a medal + fan. lol

36. rvc

by so on i meant the full question because its hard to draw here @Empty

37. Empty

@dan815 do you mean this? http://prntscr.com/7jtxyu

38. dan815

the 5,6 =>9 and 7,8=>13 makes me think maybe there is apttern with numbers its like +2 for each number ?

39. Empty

Ok what's the sequence: 1,1,2,...?

40. freckles

do i get to answer that? :p or should rvc get to answer that @empty ?

41. dan815

i am not answering these questions, its never what it it looks like with u

42. dan815

lol

43. Empty

No this is open for anyone, answer away @freckles it's all yours :)

44. freckles

it looks like the first few terms of the fibnocci sequence you have written

45. Empty

Sorry that's not it try again

46. dan815

lol

47. dan815

1,1,2,2

48. Empty

Sorry the next term in the sequence is http://prntscr.com/7jtyvr. I'll give you a medal if you can write the function for the nth term, it's a simple expression

49. dan815

1,1,2,3,4,5

50. rvc

im confused

51. Empty

Whoops I had put a period at the end. http://prntscr.com/7jtyvr

52. Empty

@rvc This problem is impossible and I'm giving an example of a problem that looks just as simple that's equally as nonsensical and ambiguous.

53. freckles

@rvc would it be against any copyright rules or laws or whatever if you posted a picture of that question? Or like even better and if not too much trouble can you copy and send the whole exam thing ? I still don't get it. Maybe I can get a better feel for the problem based on the other questions.

54. Empty

By the way the formula for the nth term of my series is starting from 0, 1,2,3, etc... f(n)=n!!!!!

55. Empty

The answer seems to be T because it's the only way to maintain the pattern that the letters are always in alphabetical order.

56. rvc

57. freckles

That is a interesting answer @Empty and is probably more possible then the other but I don't know :p

58. Empty

Yeah see this is garbage

59. rvc

60. rvc

The 14th question

61. freckles

well cookie! I'm still lost. I will have to think more about this question tomorrow because it is 1:27 AM. Sorry @rvc . :(

62. rvc

thank you so much for your effort @freckles

63. dan815

so are we agreeing on T

64. Empty

The T argument is just as good as the A argument. I'm not convinced the alphabetical order isn't just some coincidence because there's no sort of equal spacing between the letters at all.

65. rvc

so T is the ans?

66. Empty

That's not what I'm saying at all

67. Empty

I'm saying this is a terrible problem and I feel bad that this is a test question.

68. ganeshie8

lol #14 and #15 look more like reasoning problems which everybody hates because they are a bit ambiguous and not so regular mathy

69. rvc

15th is easy

70. ganeshie8

im actually trying both #14 and #15 in parallel w/o any success whats the solution for #15 ?

71. rvc

15th : |dw:1434956874159:dw|

72. ganeshie8

that's so cool !

73. rvc

yep but the 14th and 16th is not cool lol what about 12th?

74. ganeshie8

#12 should be number of black marbles in W = number of white marbles in B because whatever the new white marbles in B, they have come from the jar W

75. rvc

|dw:1434957539577:dw|

76. rvc

|dw:1434957746502:dw|

77. ganeshie8

In 3rd case, notice that you have "40 white" and "10 black" marbles in jarW. Suppose you randomly pick "x white" and "10-x black" marbles from jarW and put them in jarB. Then the number of black marbles left behind in jarW would be ?

78. jim_thompson5910

#14 This is my guess. I could be way off. aN => S eF => I gH => M flip the letters in the first part to get Na => S Fe => I Hg => M we have Na, Fe, Hg. All code names for elements on the periodic table Na = Sodium which starts with an S. So that explains Na => S Fe = Iron, so that explains Fe => I Hg = Mercury, explains Hg => M So nS turns into Sn which is Tin So I'm thinking that Sn => T which means nS => T It's the only thing that comes to mind which makes sense because it fits, but at the same time, this is chemistry material (which doesn't fit in a math test).

79. rvc

hmmm idk @ganeshie8 black marble will be 10-x =y

80. rvc

wow congrats!!!! @jim_thompson5910 Thank youuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

81. ganeshie8

wow @jim_thompson5910 that should be it xD

82. jim_thompson5910

it might be that or something way different

83. rvc

you proved it

84. rvc

85. ganeshie8

For #16, you may use 30-60-90 triangle |dw:1434959042367:dw|

86. rvc

what should i do next @ganeshie8 ?

87. ganeshie8

use 30-60-90 triangle or directly go for trig to find the lengths of other sides in that right triangle in terms of R

88. rvc

|dw:1434959598398:dw|

89. rvc

90. jim_thompson5910

@rvc, do you see how point C is R units away from A? The question is pretty much answered at this point

91. rvc

yep i found that :) thank you so much @jim_thompson5910

92. rvc

@jim_thompson5910 what about the 12th one?

93. rvc

@mukushla

94. anonymous

So exercise 12 is about probability...

95. rvc

yep

96. anonymous

hi, I can't understand the question

97. rvc

:/

98. rvc

which one ? the 12th one? did you see that file?

99. anonymous

Alright! Let the number of white balls in Box W be 40 whites and that in box B, 40 black balls. After ten black balls being transferred to box W, the probability of encountering a white ball at any pick is $P _{w}=\frac{ 40 }{ 50 }$ and that of encountering a black one is $P _{b}=\frac{ 10 }{ 50 }$. - The number of black balls in W could be = to the number of white balls in B, because possibly, 10 white balls could be put in box B, hence having 10Black in W and 10 White in B. - The number of black balls in W can be more than the white balls in B after ten picks, if for instance 7 black were picked and 3 white were picked. - Similarly, the aforementioned explanation works for the 3 case. - The last alternative would be incorrect.

@rvc?

sorry to keep u waiting i was afk gtg i appreciate ur help ;)

102. mathmath333

Wow jim thopson's answer was amazing!
