Logical Reasoning (MTS) Sitting Arrangement

Five professors A, B, C, D and E are sitting in a row facing the North (not necessarily in the same order). A is second to the left of

D. Only two professors are sitting between C and E. No professor is sitting to the right of E.

How many professors are sitting to the left of D?

This questions was previously asked in

SSC MTS 13th July 2022 Shift-3

Let’s break down what we know:

- No professor is to the right of E ? E is at the extreme right end.

- Only two between C and E ? The row is: _ _ C _ E or C _ _ E _ (but since E is far right, only _ _ C _ E is possible).

- A is second to the left of D. That means: A _ D (so between A and D, exactly one seat).

Let's figure out the arrangement:

Seats: 1 2 3 4 5

- E has to be seat 5.

- If C is two seats left of E, C must be in seat 3: _ _ C _ E

- Now, only A, B, D left. A is second to left of D, so if D is in seat 4, A should be in seat 2. Let's check:

1 2 3 4 5

_ A C D E

Who’s left? B goes in seat 1.

So, the order is: B, A, C, D, E

Now, how many professors are to the left of D (seat 4)? Count: B, A, C. That’s three.

Let’s look at the options:

- Option 1: 3 (This is right)

- Option 2: 0

- Option 3: 2

- Option 4: 1

Bottom line: There are three professors to the left of D. The correct option is Option 1: 3.
