Dear student
 
frequency of unknown tuning fork will be = 288 +4 = 292 Hz   or   288 – 4 = 284 Hz
 
on placing a little wax on unknown tuning fork, its frequency decreases but now the number of beats produced is 2 i.e. the frequency difference now decreases. It is possible when frequency of unknown tuning fork  = 292 Hz
