10. Which course has only one coordinator and only one support professor?

1) Marketing 2) Finance 3) Operations

4) Strategy 5) None of these

1. 2; P < W > R = S < T < K

P < W > R = S < K

Combining

R < K

So, K > R is true.

Now,

P < W > R < K

Proved above

W and K cannot be compared

So, option (2) is not definitely true.

Given S < T < K

Combining

S < K

So, (3) is also true.

Again, R = S < T < K

R < T < K

So, (4) is also true.

2. 5; I is true because All lions are tigers. II is also true for the same reason.

3. 5; Some motors are scooters + No scooter is a vehicle = I + E = O = Some

Motors are not vehicles. That leaves the possibility of I. No scooter is a vehicle (E) – conversion – No vehicle is a scooter (E) – implication – some vehicles are not scooter (O). Hence II follows.

4. 5; All stars are planets + No planet is a moon = A + E = E = No star is a moon. Hence I follows, No planet is a moon (E) – conversion – No moon is a planet (E). Hence II follows.

5. 1; Note that there is no negative statement.

(6 - 8):

The machine rearranges one number at the left end and one word at the right end. Numbers are arranged in ascending order at the left end from right to left. Similarly words are arranged in alphabetical order at the right end from left to right. In each step one number and one word in rearranged. This process is repeated till the final arrangement.

Input: sure 72 create 39 17 fever ultra 65 81 wind

Step I. 17 sure 72 39 fever ultra 65 81 wind create

Step II. 39 17 sure 72 ultra 65 81 wind create fever

Step III. 65 39 17 72 ultra 81 wind create fever sure

Step IV. 72 65 39 17 81 wind created fever sure ultra

Step V. 81 72 65 39 17 create fever sure ultra wind
