Hello Pradeep,
I saw your message more than a year late. I have discovered that the Word problems are solved better by dividing them into two - comprehension and the mathematical part.
As a first step, I re-read the problem with my students, explaining the problem in day to day language (practical application), then I make them focus on the Mathematical ( Calculation) part of it.
The typical tough question in Algebra is the 'Age question' - My father's age is twice my age at present, It was 4 times 10 years ago and will be 1.5 times in 5 years from now ( This is not a correct question, but is being used for illustration).
In this question, current age is denoted by 'x', ten years ago gets replaced by 'x-10' and 5 years from now get replaced by 'x+5'. These are equated to the relevant ages of the father (2x to begin with). A substitution is done to arrive at the solution.
Hope I have been able to clarify. I am located in Delhi. Do let me know if you need more assistance, we can talk thru SKYKE or on phone.
