Hi Friends, For Hand Shake Problems Four Types: N given no of people. ‘No cyclic’ sequence “n-1” will be the answer ‘Cyclic Sequence “n” will be the answer how many set they are asking “ n/3” will be the answer hand shake with each other n(n-1)/2 will be the answer A person run from A to B.He took ¼ of the time less to reach B when compare to run at normal Speed.Then how many percentage he has increased his speed? Suppose the person take ‘x’ hours. Now take only ‘ 3/4x’ time only…. Time 4x:3x They are asking speed so speed and time are indirectional proportational Now indirectional so, speed 3x:4x Speed percentage= x/3x * 100; i.e., 100/3 =33.33% If a pipe can fill the tank within 6hrs.But due to leak it takes 30 min more. Now the tank is full then how much time will it take ...
