Unless we can assume that all students take tea, or coffee, or both, then we do not have enough information in the facts given.
All we know competely is the details regarding tea.

14 take tea and 10 of those do not take coffee.
This tells us that 4 people who take tea do also take coffee.

But, this leaves 16 people who definitely don't take tea ....
