Hi Aarti,
In order to find the solution of this problem consider 4 types of number: 4k, 4k+1, 4k+2, 4k+3
Sm = m(m+1)(2m+1)/6
Now take the first number,
It contains 4, 8, 12, 16, 20...., 100
In this set all the multiples of 8 would satisfy the condition, ie, 8,16,24.....,96. Total of 12 numbers
Now if you insert 4k+1 and 4k+2 seperatly in this formula, the resulting answer won't be divisible by 4.
Now insert 4k+3 in this formula, you will get numbers 7,15,23.... till 100 in this set. Total numbers in this set = 12
Total numbers in both the set = 12+12 = 24

not possible?

210.

There is a straightforward way... Please correct me if I'm wrong...

Let x be the distance traveled at the decreased speed. So the decreased speed can be equated as :

x/(10 hours) = (x-70)/(9 hours)
Solving,
9x = 10x - 700
i.e.,
x = 700, which is 70% of the total distance covered.

So, total distance : 1000km.

yes, provide the solution

Hi Vaibhav,

The number of zeroes at the end of what? :-)

Hi Swaroop,
In the fist case, take m = 1, u = 1, v = 2, w = 3
Then m = minimum of {1,2,3}
In the second case take m = 2, u = 3,v=4, 2=5
mThe answer should be D

but how c would be eliminate??

Hi Swaroop,
In order to solve these type of questions suppose the value of (y+5)/(y^2+5y_25) = k
ky^2+(5-k)y+(25k-5) = 0
Discriminant>=0
Hence you will get the 2 values one minimum and another maximum

i am facing with minimum values or maximum values question how to tackle these?? any videos on cracku??

Hi Avala,
In order to solve para jumbles, you need to keep in mind few points. Firstly you need to understand the chain of thought and hence identify the opening or closing sentences. Look for transition words. For eg. If in the starting of a sentence, "But" is used, it is understood that the sentence preceding this is contradictory to the given sentence. Also look out for chronology and cause and effect statements. For eg look out for the word Hence, As a result of in order to identify preceding statements.

Driver spend 30 rupees on trip and makes 20 percent profit then he /she earns 36 rupees due to which he/ she earns 12 ruppes/passenger ,now he/she has 4 passenger then he/she earns 48 rupees(12/passenger) and spend only Rs 24 so profit equal to 24 and percentage is 100 percent

I don't know the answer. Someone, Please help with this

Hi Swaroop,

The basic concept in Out of Context questions is the same as that in Para Jumbles. You have to understand the context of the paragraph. Once you understand what the author is talking about, try to eliminate the sentence that is not talking about the same thing that the other sentences are talking about. Once you do that, rearrange the other sentences to form a coherent paragraph. If these sentences do not make sense as a paragraph, probably the sentence that you eliminated is not the correct one. This test should be performed without fail. By following this procedure, you can get the out of context sentences correct.

on y = 1, there are 37 points
y = 2, there are 33 points
y = 3, 29 points
y = 4, 26 points
y = 5, 22 points
y = 6, 19 points
y = 7, 15 points
y = 8, 12 points
y = 9, 8 points
y = 10, 5 points
y = 11, 1 point
Total = 204 points
