Ans of last ques: A 10 min., B 15 min. , LCM (Capacity is 30 litres), and efficiency is 3 (A) & 2 (B) respectively. Now when he expected it to fill.. leakage pipe was open.. so he closed it and it took 4 mins more to fill 30 litres (capacity). 4 mins. = (3+ 2) x 4 = 20 litres. So at the time he came to check it was 30-20 = 10 litres. So, we get (A+B-C) x 6 min. = 10 or (5-C) x 6 = 10 or C= 20/6. This is the efficiency of C or we can say this is the amount C is taking out per min. Now they are asking about the time in which tank will be emptied completely. Capacity of tank/Efficiency of C = 30 divided by 20/6. 9 will be the answer.
