Hello readers, here is a problem shortcut trick for a type
of question which is mostly asked in many competitive exams like cat, mat,
gate, ssc, ibps etc.

**The Question Given below was asked in GATE 2013 also this type of questions are asked in many Competitive Exams. Through this trick, you will be able to solve that question in just 2 seconds.**

These types of questions are very difficult
to solve and might take 5-15 minutes to solve depending on the mental
capability of the candidate. This type of questions has been asked several
times in various exams as said above and most of the candidates are not able to
solve them or if some of them are able to solve it, they would have spent a lot
of time solving these questions.

What normally a candidate does to
solve this types of questions is that the candidate will calculate the square
root of 12 and will add up all the square root values so that he/she can reach
to a nearest answer. But this process will take a big deal of time as this
process is lengthy and will consume 5-15 minutes or more. But in competitive
exams you don’t have that much sufficient and if you spend this much time in
solving this type of question, you can also think that you can solve 5-10 other
questions easily by leaving this type of question. But with this trick you will
be able to solve this type of question in just 2 seconds.

So what I am discussing here is the
shortcut trick to solve this types of question and this trick will solve this
type of question in just 2 seconds.

Here is an official video of this trick
in which I have fully explained this trick.

Here is also I am explaining this trick

So friends, if in this type of question,
we imagine 12 as x. also x should be given even as 12 is even.

The answer will come when we equate x to
n(n+1) i.e.

x=n(n+1)

in the above question, x is even and its
value is 12. So think about those factors of 12 which make it equal to n(n+1)

those factor can only be 3(3+1) means
3x4=12. the answer will be the bigger number means n+1

SO THE ANSWER WILL BE 4

Means the answer will be n+1 means 4.

So it just takes 2 seconds to solve this
question as you just have to think of the factors of the given number and you
get the answer.

Here is the question that was asked in GATE 2013 and this types
of questions are very important in competitive exams.

Question:

{1/(√1+√2)}+{1/(√2+√3)}+{1/(√3+√4)}+……+{1/(√80+√81)}

Solution:

Decrease the first term from the last term

i.e.

√81- √1= 9-1= 8 answer

This is the fastest trick for this type of questions among
all types of trick. And you can solve them in just 2 seconds using this trick.
If you don’t use this trick and apply other types of tricks, you will be
wasting time in the exams. And time is
money.

So be fastest and learn the best trick only on MeriView.in
