Explanation:

Let’s break down the statements one by one:

- P's birthday is in January.

- R must have equal people before and after, so R must be in the 4th month (May).

- Only one person between S and R. So S is either April or June.

- Q's birthday is in a 31-day month but not August (So can be Jan, Mar, May, July).

- Two birthdays between Q and V (can be before or after).

- T's birthday is before U's birthday.

- Q's birthday is not before R; so Q is in or after May.

Let's assign months to birthdays:

Jan - P

Mar - (open)

Apr - (open)

May - R

June - (open)

July - (open)

August - (open)

Q: not August and must be May, July, Mar, or Jan.

Since R is in May and P is in January, Q can be July or March.

But "Q's birthday is not before R" ? Q must be July or August (since May is R and March is before R).

But Q can't be August ("not in August"). So, Q's birthday is in July.

Now, S is one month before or after R, so S is April or June.

Let's place S in April and check:

Jan - P

Mar - (open)

Apr - S

May - R

June - (open)

July - Q

August - (open)

Now, Q and V have two people between them. Q is July, so V can be April or October (but we only have till August). April is S's.

Try V in March:

Jan - P

Mar - V

Apr - S

May - R

June - (open)

July - Q

August - (open)

Now left are T and U for June, August.

With "T's birthday is before U's birthday," T must have June and U must have August.

Final Order:

Jan - P

Mar - V

Apr - S

May - R

June - T

July - Q

August - U

How many persons have their birthday before Q (July)?

- Jan (P), Mar (V), Apr (S), May (R), June (T) ? 5 people before Q

Option Check:

1. One

2. Two

3. Three

4. Four

5. More than Four

Correct Answer:

Option:5- More than Four

Explanation Recap:

- Each person fits uniquely to each month.

- R in May splits the group evenly.

- Q must be July. Five have birthdays before July: P, V, S, R, T.

- Option 5 is correct.
