The total time to take empty the ship is
Explanation of Solution
Given Pump A take total time to unload the Lunar petro is 30hr.
Pump B take total time to unload the Lunar petro is 24hr.
Work done by pump A in one hour is
Work done by pump A in
Similarly
Work done by pump B in one hour is
Work done by pump B in
Suppose total work done by both pump is 1
Express the equation of work done together
Multiply both the sides by 120, the LCM of 24 and 30
Simplify
Hence, The total time to take empty the ship by both pump is
