Vishal84,

A tip I recently discovered for data sufficiency problems is below:

In order for an equation to be sufficiently solved there needs to be at least as many equations as there are variables. So, for example, if you have 3 variables you will need at least 3 different equations to be provided for the questions to be sufficiently solvable.

This tip is very specific and might be a bit too narrow but it really helped me on a few data sufficiency questions.

I hope this helps you out!

Also..be carfeful of equations that are the same, but are factored differently, etc to look diffferent..common trick...
