Pipe A can fill in 20 minutes and Pipe B in 30 mins and Pipe C can empty the same in 40 mins. If all of them work together, find the time taken to fill the tank. The Answer is A. You are given 8 identical balls.... Ans: Divide 8 balls in groups of 3-3-2. Say they are named A, B, C. First trial ----------- Now compare A and B. Compare two balls of C. Second Trial ------------ If A! Say balls of group A are named 1, 2, 3. There were 2 doors. But the lier will say B Case 2: Question asked to the man who tells truth The lier will pick B. And the true man tell the truth. So both will pick B. The letters A, B, C, D, E, F and G, not necessarily in that order, stand for seven consecutive integers from 1 to 10 D is 3 less than A B is the middle term F is as much less than B as C is greater than D G is greater than F 1. A is as much greater than F as which integer is less than G a A b B c C d D e E 3. If a vessel contains 56 lit of a mixture of milk and water in ratio3:2. In a Bus there are 7 people. Each one carry 7 bags. Each bag contains 7 cat. Each cat carry 7 small cats. How many legs are there in the bus? There are 12 balls looks identically equal. But one of them has weight different more or less from other. How to find that dissimilar ball with minimum balances? Ans: Divide 12 balls as A-4,B-4,C-4 Compare A and B If equal then Divide C-4 into two parts link C1-2,C2-2 Divide C1-2 into Two Parts and Compare, Now we can find Different One If not, Divide C2-2 into Two Parts and Compare, Now we can find Different One If A and B is not equal then Divide A into two parts and compare or Divide B into Two parts and Compare. Finally proceed the above step to get the Result. There are Four Identical comparisons to be taken in this experiment. There are 7 letters A,B,C,D,E,F,G All are assigned some numbers from 1,2 to 7. B is in the middle if arranged as per the numbers. A is greater than G same as F is less than C. G comes earlier than E. Ans: Correct Answer is 8.
