Given : Three pipes A, B & C can fill a tank in 300 min, 360 min & 480 respectively
all the pipes are opened simultaneously
To Find : how long will it take for the tank to get full
a) 122 min b) 130 min c) 135 min d) 150 min
Solution:
pipe A fill in1 min= 1/300
pipe B fill in 1 min = 1/360
pipe C fill in 1 min = 1/480
All together fill in 1 min = 1/300 + 1/360 + 1/480
= (1/60) ( 1/5 + 1/6 + 1/8)
= (1/60) ( 24 + 20 + 15) /120
= (1/ 7200) (59)
Time taken to fill tank = 7200/59
= 122.03
= 122 mins
