Answer 1

Let the Tank to be Filled be : T

Given that A Inlet alone can fill the Tank in 30 mins

⇒ In One Minute A Inlet fills T/30 of the Tank

Given that B Inlet alone can fill the Tank in 40 mins

⇒ In One Minute B Inlet fills T/40 of the Tank

Given that C Inlet alone can fill the Tank in 60 mins

⇒ In One Minute C Inlet fills T/60 of the Tank

⇒ In One Minute A - B - C inlets Fill : T/30 + T/40 + T/60

⇒ T/30 + T/40 + T/60 = (4T + 3T + 2T)/120 = 9T/120 = 3T/40

⇒ In One Minute A - B - C inlets Fill : 3T/40

⇒ In 40/3 Minutes A - B - C inlets Fill : 3T/40 × 40/3

⇒ In 40/3 Minutes A - B - C inlets Fill the Tank 'T'

⇒ 40/3 = 13 + 1/3 = 13 minutes and 60/3 seconds

⇒ 40/3 = 13 Minutes and 20 seconds

⇒ The A - B - C inlets Together fill the Tank in 13 Minutes and 20 seconds
