ANSWERS For Questions directions-for-questions-from-1-to-2

Answer for question  1 & 2 :- 

Let p be the number of problems on the test. 
Let n be the number of problems solved by the tenth student. 
Then n <= p. 
The number of problems solved, counted with multiplicity, is 7p 
since each student solved seven questions. 
However, we also know that the first nine students solved four questions each and the tenth solved n questions, 
so 

      7p = (4×9) +n. 


Re-arranging gives us 

p = (36 + n)/7 

Recalling that n <= p, we have

n <= p ⇒ 7n <= 7p ⇒ 7n <= 36 + n ⇒ 6n <= 36 ⇒ n <= 6.

Therefore, we are looking for non-negative n such that p = (36 + n)/7 and n <= 6

Therefore n = 6 and so p = 6. That is, the number of problems solved by the tenth 

student was six and there were six questions total on the test. Hence, option (2) is the correct choice





3.)    Given
                 (xy)z = 64
            
            
since  positive integral 
           
 Whenz = 1, xy = 64. The total number of factors of 64 is 7.
z = 2, xy = 8. The total number of factors of 8 is 4.
z = 3, xy = 4. The total number of factors of 4 is 3.
z = 6, xy = 2. the total number of factors of 2 is 2
Hence, total number of positive integral solutions is 16.



4.)  Diameter of the circle is equal to the side of the smallest
   square is πr2 = 77
  ⇒r = 3.5 (sqrt(2))
  ⇒ 2r = 7 sqrt(2) , side of the smallest square.
  Diagonal of the innermost square = 14 units.
  Diagonal of the largest square will be 14+ [(1.5) × 2] × 4
  = 14 + 12 = 26 units
  ⇒ Area of the largest square
  =  0.5 × (diagonal)2 = 338 sq units and area of the smallest square =  (7 sqrt(2) )2 sq. units.
 Required difference = 338 – 98 = 240 square units.



 5 .)  Total number of ways of dividing 24 boys in two distinct sub-sections is 24C12 = 24!/(12! 12!)
There can be two ways in which two shortest boys lie in different sub-section and correspondingly the remaining 22 boys can be divided into two distinct sub-sections in 22C11 ways.
∴ Probability = (2 x 22C11 )/24C12 = 12/23

6.)


7 ) here are 18 possible values of x and 9 possible values of y.
Since, BC is parallel to the X – axis, therefore AB will be parallel to the Y – axis.
The X – coordinate of points B and A will be same and the Y – coordinate of points B and C will be same.
For, every chosen co – ordinate of point B, the Y – coordinate of point A can be chosen in
9 – 1 = 8 ways and the X – coordinate of point A can be chosen in 18 – 1 = 17 ways.
Number of ways in which co – ordinate of point B can be chosen = 18 x 9
Total number of distinct triangles = 18 x 9 x 17 x 8 = 22032

8 .) Question

 The maximum possible area (in square units) of such a triangle ABC is ?

For maximum possible area of such a triangle ABC, the co – ordinates of point B, A and C should be


(- 8, 9), (- 8, 17) and (17, 9) respectively.


Maximum Area = (1/2) x 25 x 8 = 100 square units.


9 .)



10 )  Let, the average age of the family when the first child was born be 'x' years.
Therefore, the total age of the family when the first child was born is 3x.

Let, after a years, the second child was born:
Therefore, (3x + 3a) = 18 x 4 = 72

Let, after another b years, the third child was born
Therefore, 72 + 4b = 16 x 5
b = 2,
Let, after another c years, the fourth child was born
Therefore, 80 + 5c = 20 x 6 = 120
c = 8

Let, after another d years, the fifth child was born
Therefore, 120 + 6d = 24 x 7 = 168
d = 8.

Let, after another 'e' years the average age of the family is 28 years.
Also, 168 + 7e = 28 x 8 = 224
7e = 56
e = 8

Also, a + b + c + d + e = Present age of the eldest child = 27
a = 27 – 26 = 1 year.

3x + 3 = 72
x = 23.

Points to remember while preparing for GATE 2011

Points to remember while preparing for GATE 2011


Systematic preparation is only the way to qualify the GATE 2011 and all public sector exams. Following these suggestion for success in GATE and public sector exams.

1. Bring previous year GATE exam question papers (gate exam questions are available very easily in the market).
2. Start back study (i.e. pick up GATE questions and find the solution) I personally believe if you practice to solve all the gate questions from the previous asked (at least 6-8 year) you can definitely qualify the gate exam.
3. Another important fact is: do not answer wrong during the gate examination even your total score is only 35 to 45 % (mostly people could not qualify gate exam because they attempt to answer wrong question).
4. Keep in mind, most of the time negative marking is only responsible to the failure.
5. Join some Gate exam discussion and online sharing forum and discuss your doubts and get touch with Gate Aspirants.
I hope if you follow all these suggestion you will definitely qualify GATE exam.

Preparing for GATE 2011 can be made easy in 10 steps

Preparing for GATE can be as easy as preparing for your college examinations. Just take little cautions while studying any topic and do remember that GATE paper focus on your in depth knowledge of subject, your basics, presence of mind during examination etc.


1. Always follow standard books for GATE. Try to cover complete syllabus. If not possible expertise in what ever portion of syllabus you practice.

2. Try preparing notes after reading every chapter topic. This may initially take some time but will help you while revising before paper.

3. While reading any chapter topic does ask your self following questions What, How, and why and see improvement.

4. Best way to prepare is to follow cycle Learn, Test, Analyze, Improve, Learn, Test, Analyze, and Improve.

5. Do remember that GATE is completely objective question based test. Most of time solving objective questions is tricky. Learn tips to solve GATE objective questions.

7. In case of doubts do ask some expert or use forums to discuss questions as provided by httpwww.indiastudychannel.com or ask me.

8. Don’t worry if your percentage in university exams is low as GATE admissions do not consider them. Just maintain minimum percentage required by many colleges including IIT’s. Look at GATE Cutoff and eligibility section to know eligibility and cut off of various colleges.

9. Group study is one of the best ways of preparation. Divide sections topics between you and your partner and have a brief session on topic from your friend before you actually start topic. This will save your time and efforts and will improve your and your partner’s understanding on the topic.

10. Normally coaching GATE is not required but if you are not able to concentrate much then this is a good option.

GATE – 2011 Preparation Tips

GATE – 2011 Preparation Tips
1. Material Collection
  • Syllabus
  • All the relevant books based on the subject(Divide the books in two groups - (1)Fundamental and basic concepts (2)Problem oriented
  • Some books helpful for pre-requisite knowledge on the subject
  • Some good guide books for GATE
  • Previous questions papers
2. Keep contact with some expert and GATE experienced persons
3. Study - Syllabus and Previous questions papers
4. Start from the first chapter
  • Read at least 5 books, it will widen your knowledge(if necessary consult with the books for pre-requisite knowledge or with some expert)
  • Note down the probable concepts (definitions, unit, dimension etc.)
  • Note down necessary theories, formulae etc
  • Solve problems as maximum as possible(from text books, Guide books etc)
  • Think about various tricks in solving problems(if necessary, note it)
  • Go for series of self tests based on this chapter(take other's help to conduct tests)
  • Continue the self tests until getting a very good score
5. Solve more and more problems, discover more and more new tricks…
6. Follow the same procedure for the rest chapters
7. Finally, go for self tests based on whole syllabus(take other's help to conduct these tests)
8. On the exam day…you will be at the Pick, who can stop you?
