I think there is a tricks behind all the mathematics problem and you have to just know the tricks. Only then it is possible to crack IITJEE/AIEEE/WBJEE and all other entrance exam. Always you have to remember an important fact that is time factor. One can solve a sum in a broad way, but he/she will not be able to attempt maximum numbers of sum. But if he/she can apply my tricks I am 110% sure that she/he will crack the entrance. Here i want to show you some example of that types of tricks

Suppose your question is like___________

IF (a2.a3/a1.a4)=(a2+a3)/(a1+a4)=3.{(a2-a3)/(a1-a4)}then a1,a2,a3,a4 are in?

1. AP 2. GP 3. HP 4. NONE

Tricks : you need not do anything, just let they are in AP

so put a1=1, a2=2, a3=3, a4=4 and check the above relation. if it is true then they are in AP. If they are not in PA, then let they are in GP and put a1=1, a2=2, a3=4, a4=8 and check again. if it fails let they are in HP and put a1=3, a2=4,a3=6, a4=12.

For the above sum you will see HP is the correct answer.

So it is very easy.
