Read the given information carefully and answer the related questions:

Seven persons P, Q, R, S, T, U and V - do different activities in seven different months i.e., January, March, April, June, July, August and November. The activities are – Yoga, meditation, dancing, hiking, cycling, camping and reading. Cycling is done in the month of 30 days. Three persons are in between S and the one who does cycling. One person is in between S and T. Number of persons after T is same as before the one who does Yoga. P is just before the one who does dancing. More than three persons are in between P and V who does meditation. Hiking is done in the month of 30 days before R. Reading is done before Q who does not do hiking.

Who among the following does his activity in June?

To find out who performs their activity in June, let us analyze the clues step-by-step by listing the months in chronological order along with the number of days in each month:

1. January (31 days)
2. March (31 days)
3. April (30 days)
4. June (30 days)
5. July (31 days)
6. August (31 days)
7. November (30 days)

Step 1: Determine the positions of Cycling and S
- Cycling is done in a month with 30 days (April, June, or November).
- There are exactly three persons (months) between S and the person who does cycling.
- If Cycling is in April, S must be in November. If Cycling is in November, S must be in April. (If Cycling is in June, there cannot be three months between them).
- One person is between S and T. If S is in November, T must be in July. The number of persons after T (2 persons: August and November) must equal the number of persons before the one who does Yoga. This means Yoga must be in April. However, if S is in November, April is already occupied by Cycling, which is a contradiction. Hence, S must be in April, Cycling is in November, and T is in July.
- Consequently, Yoga is done in April by S.

Step 2: Position P and V
- P is scheduled immediately before the person who does dancing.
- V does meditation, and there are more than three persons (at least 4) between P and V.
- To have at least four months between P and V, they must occupy January and August. Since V does meditation and November has Cycling, V cannot be in November. Thus, V is in August (doing meditation) and P is in January.
- Since P is just before the one who does dancing, dancing must be in March.

Step 3: Place the remaining persons and activities
- Hiking is done in a 30-day month before R. The only remaining 30-day month is June. Thus, Hiking is done in June, and R must be scheduled after June. The only vacant spot after June is November. So, R is in November (doing cycling).
- Reading is done before Q. Since Q does not do hiking, Q cannot be in June. Thus, Q must be in March (doing dancing), leaving June for U.
- Therefore, U does his activity (hiking) in June.
