Answer: B) 8 hours Explanation: Efficiency of Inlet pipe A = 4.16%       10024    Efficiency of Inlet pipe B = 5.83%      1001717     Therefore, Efficiency of A and B together = 100 %      Now, if the efficiency of outlet pipe be x% then in 10 hours the capacity of tank which will be filled = 10 *  (10 - x)   Now, since this amount of water is being emptied by 'C' at x% per hour, then    10x10-xx=2.5 hrs   => x = 8    Therefore, in 10 hours 20% tank is filled only. Hence, the remaining 80% of the  capacity will be filled by pipes A and B  in 80/10 = 8 hours
