While solving the GMAT problems, I am facing a problem of assuming information.. For example, in the below question, it is mentioned that the increase is 'constant amount'. But when I read this question, I assumed it is constant rate of increase, and complicated a simple problem.

This happens to me in considerable number of problems in verbal and quant. Could somebody help me on how should I work on this, please?

Example Question:

when a certain tree was first planted, it was 4 feet tall & the height of the tree increased by a constant amount each year for the next 6 years. at the end of 6 year the tree was 1/5 taller then it was at the end of 4 year. by how many feet did the height of the tree increase each year

a 3/10

b 2/5

c 1/2

d 2/3

e 6/5

This question is already discussed here:
