Edward's home have 3 taps,One tap, working alone at its maximum constant rate, can fill a certain sink in 270 seconds.A second tap working alone at its maximum constant rate, can fill a certain sink in 274 seconds. A third tap, working alone at its maximum constant rate, can fill the same sink in 276 seconds. If all taps work together at their respective maximum constant rates, the time it will take to fill the sink is closest to	Answers:	A) 91 seconds	B) 102 seconds	C) 177 seconds	D) 200 seconds	E) 270 seconds
Tap 1 : 270 secs   Tap 2 : 274 secs   Tap 3:276 secs   Considering the average of these 3 taps : 273.33 secs.   So 1 tap can fill the tank in 273.33 secs, so 3 taps can fill the tank in 273.33/3=
