I think there is a lack of information with regards to the question posted above. This may be the complete question:

Van is 75% taller than Keith. If Van's height increases by 40% while Kieth's increases only by 25%, by what percent is Van taller than Kieth now? 

We put Van at 175 and Kieth at 100 since Van is 75% taller than Keith.
When Kieth's height increased at 25%, he is now 125
When Van's height increased at 40%, he is now 245

245-125=120 and

120/125= .96 = 96%

The answer is 96%. I hope this helps.
