Hi Sahithi,

sahithi pallavi

1.One of the following is my secret word:AIM DUE MOD OAT TIE.With the list in front of you, if I were to tell you any one of my secret word, then you would be able to tell me the number of vowels in my secret word.Which is my secret word?

I think "BOLD" line above is confusing. It should be: "if I were to tell you any one of my secret letters".

Answer will be TIE.

Thanks

Hi Sahithi,

sahithi pallavi
hai friends...!I am waiting for 4th and 6th answers...!

English-Scared has already answered your 6th question correctly.

For 4th question which is:-

4)In the following figure:
       A       D
       B   G   E
       C       F
   Each of the seven digits from 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 is:
  a)Represented by a different letter in the figure above.
  b)Positioned in the figure above so that A*B*C,B*G*E, and D*E*F    
       are equal.
Which digit does G represent?

Answer: G is 2

Quick reasoning:- 0,5 and 7 could be removed because:-

Cannot be 0 => At max 2 products could be made zero but not all three.
Cannot be 5 => At max 2 products could be made to have 5 or 0 at Ones place but not all three.
Cannot be 7 => This is the single number which has got none of its factors common with other numbers.

From remaining: 1 2 3 4 6 8 9 we need to distribute:-

Seven 2's; Four 3's and One 1.

Can be done as follows:-

3   1
4 2 9
6   8

Therefore G is 2.

Hi Sahithi,

sahithi pallavi
now the two questions are::

7) Pipe A can fill in 20 minutes and Pipe B in 30 mins and Pipe C can empty the same in 40 mins.If all of them work together, find the time taken to fill the tank

(a) 17 1/7 mins
(b) 20 mins
(c) 8 mins
(d) none of these

Answer: (a) 17 1/7 mins
Workout:-
Assume container to be of 120 ltrs.
A's filling rate = 6 lt/min
B's filling rate = 4 lt/min
C's filling rate = - 3 lt/min

When all 3 work together, Net filling rate = 6+4-3 = 7 lt/min

Time to fill 120 ltr vessel = 120/7 = 17 1/7 mins

[/QUOTE]
8)Thirty men take 20 days to complete a job working 9 hours a day.How many hour a day should 40 men work to complete the job?

(a) 8 hrs
(b) 7 1/2 hrs
(c) 7 hrs
(d) 9 hrs
[/QUOTE]

This question is not clear.
How many hour a day should 40 men work to complete the job? In how many days???

If it is 20 days then none of the answer matches.

Work out is:-

Men hours needed to finish work = 30 x 20 x 9 = 1800 Men-hours (MH)

If 40 Men work for "H" hours per day for "D" days,
Total Men hours = 40HD

40HD = 1800

If D = 20 days, Answer = 6 3/4 hours.

Please recheck your question.

Thanks

9) Mr. Shah decided to walk down the escalator of a tube station. He found that if he walks down 26 steps, he requires 30 seconds to reach the bottom. However, if he steps down 34 stairs he would only require 18 seconds to get to the bottom. If the time is measured from the moment the top step begins to descend to the time he steps off the last step at the bottom, find out the height of the stair way in steps?
A) 45 steps
B) 46 steps
C) 47 steps
D) 48 steps

10) The average age of 10 members of a committee is the same as it was 4 years ago, because an old member has been replaced by a young member. Find how much younger is the new member ?
A) 30 years

D) 45 years

@itchap-RKJQDB • Aug 19, 2009

Qnswer for question.9

Let the speed of escalator be x steps/sec

then total steps in escalator is 26 + 30x (since the escalator covers 30x steps while the person covers 26 steps)

Similarly the in the second case the total no of steps is 34 + 18x

solving both .. 26 + 30x=34 + 18x
=>12x =8
=>x= 2/3
therefore steps is 26 + 30*2/3 =46 steps

Answer will be B.)46 steps

0

@itchap-RKJQDB • Aug 19, 2009

Answer For Question 10

The average age of the group is calculated by adding up all of their individual ages and dividing by the number of members, in this case 10. Four years later, all of the members are 4 years older so the sum of their new ages is 4 * 10 = 40 more than before.

So, in order to make the average the same as before you would have to somehow subtract this extra 40. Therefore the new member is 40 years younger than the one he replaced.
So Answer will Be B.)40 Years

Answer For Question 11

Look at the series its
8 2 14 6 11 ? 14 6 18 12
Now add the 1st number and the last number .. it is 20.
not add the 2nd number which is 2 and the last but one number which is 18 ... it is 20..
So if you keep adding these all the sum equals to 20. So the number next to 11 should be 9.

here are the answers::

17) Solve for x and y: 1/x - 1/y = 1/3, 1/x2 + 1/y2 = 5/9.

A) x = 3/2 or -3 and y = 3 or -3/2.
B) x = 2/3 or -3 and y = 3 or -2/3.
C) x = 3/2 or -3 and y = -3 or 3/2.
D) x = -3/2 or 3 and y = 3 or -3/2.

18) Why we use " i.e " instead of " that is" ?

Ans : "i.e." is an abbreviation for the Latin words, "id est", which roughly means, "that is". It is commonly used as a conjunction to join two clauses.

17 .Thats a simple calculation correct..

1/x - 1/y = 1/3 , 1/x2 + 1/y2 = 5/9

(1/x - 1/y)^2 = 1/9 = 5/9-2/xy

Which results in x = 9/2y

2y/9 - 1/y = 1/3

(2y^2 -9)/9y = 1/3

on solving this we get y = 3 and -3/2

such that we can solve for x as 3/2 and -3.

19 . A

Solution: For the value we need to equate the F'(x) or F'(y) = 0 we get the solution.

Here is the solution..
so x2y3 =6
so x = 6^1/2.y^(-3/2)
3x+4y = F(x)
54^1/2.y^(-3/2)+4y
F'(y) = 4 + 54^1/2.(-3/2).y^(-5/2)=0
((54*9)/4) ^1/2.y(-5/2) = 4
squaring on both sides
we get 27*9/2 *y^-5 = 16

On solving this we get y = 3/2

Substituting value in Equation we get x = 4/3

So the answer is 10.

Good Question 😀

Well the proof for 27th is by the formula x^2+y^2=(x+y)^2-2xy.substituting we get 23

or 28th:14*(2men+7boys)=11*(3men+6boys).
from this we wil get a relation between men and boys as no.of men=2*boys.
=>11 boys (2*(2*boys)+7boys) can do the work in 14 days thrfore 22boys(which is req.i. 8men +6boys) can do the work in (11*14)/2=7 days.3 times of work =7*3=21.

A)NALHK
B)PCNKM

The answer is A) NALHK.

Solution : TANGO - NFMZS
the letter before T is S
TANGO - NFMZS
the letter before A is Z
like that the word TANGO is coded as NFMZS.

APPLES - RDKOOZ
the letter before A is Z
like that the work APPLES is coded as RDKOOZ.

Now, LIMBO -
the letter before L is K
the letter before I is H
the letter before M is L
the letter before B is A
the letter before O is N

so the word LIMBO is coded as NALHK.

i hope its right.

write down A to Z in circular fashion

now wirte down the alphabet preceeding the letter
S is preceeded by R
E is preceeded by D
L is preceeded by K
P is preceeded by O

the remaining work is 3-(4/3)=5/3
black works for six days=6/8=3/4th of work completed
left out work=5/3-(3/4)=11/12th of the work which is completed in 11 days by blue(i.e 12*11/12)

No probs..!

37) 13 = 13w/(1-w)
13(1-w) = 13w
(1-w) = w
by squaring on both sides, we get
1+ w2-2w = w2
1 = 2w
by squaring on both sides, we get
12 = (2w) 2
1 = (2w) 2

On solving using LCM method we get the solution.

1/20 = 50 .

Thus considering x , x/20 = 50
