Lazzies
Razzies
Bloops
None of the above
By transitive relation in logic, if A ? B and B ? C, then A ? C. Here Bloops ? Razzies and Razzies ? Lazzies, so Bloops ? Lazzies. Syllogism (logic)
Which of the following numbers is the odd one out? 2, 3, 5, 9
5

1
9
27
3
The rate is 1 mouse per cat per 3 minutes. In 9 minutes each cat catches 3 mice, so 3 cats catch 9 mice. This tests proportional reasoning. Ratio
Which number completes the analogy: 2 : 4 :: 3 : ?
6
12
9
