­Why 25% has not been increased on the increased on monthly salary? If it was then in the month of May savings will be achieved. ­
­

Max will earn $2,000 in January but his salary will be increased by 25% the following month. If he saves 25% of his salary every month, how many months will it take him to save $5,500 starting from January?
­
The question clearly states that Max's salary will increase ONCE by 25% the following month after January. ­

You get a GP.

Total Savings = (1/4) * 2000 + (5/4)*2000*(1/4) + (25/16)*2000*(1/4) + ...

First term = 500, common ratio (5/4)

\(\\
Sum = 500 * \frac{((5/4)^n - 1)}{((5/4) - 1)}\)

Then you will use the options to see when the sum goes to 5500.

the language of the question is not clear...whether it has increased just one time or it has increased every following month...confusing....

The wording is clear and precise. “Increased by 25% the following month” means a one time raise in February. If it increased every month, it would say “increases by 25% each month” or “every following month.”

P.S. That doubt has also been addressed HERE.
