How to prepare for Para Jumbles:

Practice, practice, practice!: A student can improve a lot in para jumbles by practicing. You get used to the process of looking for connectives and joining different threads together into a coherent chain of thought

Read: The skills used in Para Jumbles are the same as the skills used in Reading Comprehension. Therefore you should get into the habit of reading everyday. Read opinion articles in any of the major dailies. Analyze the information given in them and summarize each paragraph

Important points to note:

Main point of the paragraph: Read all sentences. Try to understand what is the main point of the paragraph. Find the sentence where the subject of the paragraph - person, event or idea is first introduced. This sentence is likely to be the first sentence or would at least be in the first few sentences.

Try to find verbal connectives: Verbal connectives like but, on the other hand, nevertheless etc provide important clues regarding the paragraph. If you find a negative connective like but, nevertheless etc find the idea being rejected in that statement. The line that states this idea would immediately precede this line. However, a note of caution : Some paragraphs can begin with connectives like However, but etc.

Try to find logical connectives: When a statement lists two reasons, or two concerns or any enumeration of this sort find the the two sentences with the reasons. These sentences should follow the line.

Analogies: If an analogy is given it should precede the real life example. For example if the author states that when a stone is dropped in water, its ripples are felt for some time after the event. If there is a sentence which gives the example of how we are still feeling the ripples of a great event, this line with the real life example must be after the line with the analogy

Definition of subject: Find lines where pronouns like he, it are used. They should immediately follow lines where this noun is defined.

sum of series of 1+2/4+3/8+4/16+..........can u please elaborate and explain it.i didnt get the solution which is already there in course..

Let S = 1 + 2/4 + 3/8 + 4/16 +...

S - 1 = 2/4 + 3/8 + 4/16 + ...

(S-1)/2 = 2/8 + 3/16 + 4/32 +...

(S - 1) - (S-1)/2 = 2/4 + 1/8 + 1/16 + 1/32 +...

= 2/4 + (1/8)/(1 - 1/2) = 1/2 + 1/4 = 3/4

So, (S-1)/2 = 3/4

=> S - 1 = 3/2

S = 5/2

a solid right circular cone is cut into 4 pieces of equal height, with each cut being parallel to its base. If the semi vertical angle of the original cone is 30° what is the ratio of the total surface area of the original cone to the sum of the total surface areas of the 4 pieces?? ans= 12:19.. approach plzz

There are 4 cones - From the original (biggest cone) to the smallest cone. Let's call them 1, 2, 3 and 4 in that order.

Let's call the four pieces A, B, C and D from the bottom to the top.

Let the bottom radius of A = 4

So, top radius of A = Bottom radius of B = 3

Top radius of B = Bottom radius of C = 2

Top radius of C = Bottom radius of D = 1

TSA of A = TSA of cone 1 - TSA of cone 2 + 2*Top area of A

TSA of B = TSA of cone 2 - TSA of cone 3 + 2*Top area of B

TSA of C = TSA of cone 3 - TSA of cone 4 + 2*Top area of C

TSA of D = TSA of cone 4

So, total TSA of all the 4 pieces = TSA of cone 1 + 2*(Top area of A + Top area of B + Top area of C)

Bottom area of A = 16 pi

So, top area of A = $$(3/4)^2$$ * 16 pi = 9 pi

Top area of B = 4 pi

Top area of C = pi

Since radius of big cone = 4, slant height = 8

So, TSA of big cone = pi * 4 * 8 + pi * 16 = 48 pi

Required ratio = 48 pi / (48 pi + 2*(9 pi + 4 pi + pi)) = 48/(48 + 28) = 48/76 = 12/19

if log(base2(5x+3y)) + log(base2(5x-3y)) = 10 where x and y are integers, the no of possible values of (x,y) is??? ans = 4.. approach plz

Hi Manini,

The solution to this question goes like this:

log(base2(5x+3y)) + log(base2(5x-3y)) = 10

(5x+3y)(5x-3y) = 2^{10} = 1024

Suppose 5x+3y = 1 and 5x-3y = 1024 or vice versa

This does not provide an integral value of x.

Suppose 5x+3y = 2 and 5x-3y = 512 or vice versa

This does not provide an integral value of x.

Suppose 5x+3y = 4 and 5x-3y = 256 or vice versa

This provides an integral value of x.

Similarly the other solution would be 5x+3y = 16 and 5x-3y = 64 or vice versa which would give integral value of x.

Hi,

Concentrate on Reading Comprehension. RC is the most important topic in Verbal. The good thing with RC is that it can be mastered with sufficient practise. Also, once you are good at RC, you will be able to solve other questions like Para Jumbles etc. easily. Solve 2-3 RC passages every day. Also, take as many mock tests as possible.

How to prepare for Para Jumbles:

Practice, practice, practice!: A student can improve a lot in para jumbles by practicing. You get used to the process of looking for connectives and joining different threads together into a coherent chain of thought

Read: The skills used in Para Jumbles are the same as the skills used in Reading Comprehension. Therefore you should get into the habit of reading everyday. Read opinion articles in any of the major dailies. Analyze the information given in them and summarize each paragraph

Important points to note:

Main point of the paragraph: Read all sentences. Try to understand what is the main point of the paragraph. Find the sentence where the subject of the paragraph - person, event or idea is first introduced. This sentence is likely to be the first sentence or would at least be in the first few sentences.

Try to find verbal connectives: Verbal connectives like but, on the other hand, nevertheless etc provide important clues regarding the paragraph. If you find a negative connective like but, nevertheless etc find the idea being rejected in that statement. The line that states this idea would immediately precede this line. However, a note of caution : Some paragraphs can begin with connectives like However, but etc.

Try to find logical connectives: When a statement lists two reasons, or two concerns or any enumeration of this sort find the the two sentences with the reasons. These sentences should follow the line.

Analogies: If an analogy is given it should precede the real life example. For example if the author states that when a stone is dropped in water, its ripples are felt for some time after the event. If there is a sentence which gives the example of how we are still feeling the ripples of a great event, this line with the real life example must be after the line with the analogy

Definition of subject: Find lines where pronouns like he, it are used. They should immediately follow lines where this noun is defined.
