Sir, I am having difficulty in solving percentage.

yeah anam saba, we had some techniques to solve percentage problems... but first let me know where you are facing the problems??? so that i can sort out your problem.....

Statements: Some oceans are seas. All oceans are rivers. No river is a canal. 23. Conclusions: I. All rivers can never be oceans. II. All canals being oceans is a possibility. 24. Conclusions: I. No ocean is a canal. II. At least some seas are rivers.

sir please answer these questions.. i am not getting them

hey prathyusha, 24 conclusions are right.... see in the 2nd statement all oceans are rivers.... that means it does not indicate that all rivers are oceans.... and from that 3rd statement it is clear that no link between canal and river.... so it clearly tells that ocean also not having any link with the canal..... and it can be have some link with the sea.....clearly we can define this by drawing U circle in sets... i can post you the pic ping me through gmail praveenkmr715@gmail.com this mail is only for study purpose

how are people scoring 98 and 81 in a timed test of 60 mins?

hey jigar, that`s all because all comes by practice... by seeing the problem if we find the logic it wont take much time to tackle the problem... so spend more time solving different models and sure you too will reach that scores....

3^√x+4^√x=5^√x Kindly, Solve this by process.

The most simple method is to see the options, let's say, an option is available saying x=4. Try substituting this in the above equation, 3^(x^0.5)+4^(x^0.5)=5^(x^0.5)3^(4^0.5)+4^(4^0.5)= 3^2+4^2=9+16=255^(4^0.5)=5^2=25Therefore, LHS=RHS

how do i solve english comprehension

@praveen sir how do we know that this point should be considered important?

while reading the comprehension mark the important points by a side so that while taking the question you will find easily that point to tackle it..... try it if you find difficult again i will help you.....

HELLO, I FEEL THAT I M WEEK IN MATHS AND MY SPEED IS SLOW I FEEL NERVOUS BECOUSE OF IT IS THAT POSSIBLE TO CHOOSE ONLY LIMITED CHAPTERS WHICH IMPROVE MY SPEED AS WELL AS I SCORE MORE

hey RENU , don't see maths like a dangerous thing.... first stop fearing about that... start your preperation from basics and solve every problem in many number of ways possible... so that you will get some self idea which makes you to get confidence on the subject..... mostly concentrate on percentage, speed distance time , time and work etc.... mostly on the aptitude topics.... it will build your score well in the exams... further if you face any problem in solving the question post the question i will sort your problem....

which is the prime colour

any of a group of colours from which all other colours can be obtained by mixing.

please provide me some short tricks for para jumble

you have to check whether the rearranged sentence having logically sense or not... for to get more comfort you have to work for more time on solving some para jumble examples..

How to find whether 2^n + 1 is prime or not?

2^n + 1 is not a prime... because by taking n=3 we will get result as 9 which is divisible by 3to find whether the number is prime or not we had a techniquelets take an example... lets take 37.... check whether its prime or notanswerlets start taking 1st prime 237 is not even, so 2 is not a factor of 37now take next prime 3and 37/3 is 12.3333 so 3 does not divide exactly into 37 eithernow next prime 5and 37 does not end with 0 or 5 so 5 is not a factor of 377 is the next prime,but it is bigger than the square-root of 36, so we can stop now.So 37 has no factors (except 1 and 37 of course) and therefore37 is a prime number.

Sir, can you work the same method for 2^256 + 1 and 2^445 + 1. TIA
