Eight friends A, B, C, D, E, F, G and H have to deliver lectures on either the 6 or 17 of four different months among January, March, April and July but not necessarily in the same order. Not more than 2 persons will give a lecture in a month. Only one person will deliver a lecture each day. A delivers his lecture on the 6 of a month which has only 31 days but not in the month of March. E delivers the lecture immediately after B. Only three lectures were delivered between A and B. Only two persons give lectures between F and C and C is not the last one. The number of persons who give the lecture after E is the same as the number of persons who give the lecture before F. G and C give their lectures in the same month. D gives the lecture before H.
Who deliver the lecture on 6th March?
G

- Eight friends (A, B, C, D, E, F, G, H) deliver lectures, each on either the 6th or 17th of January, March, April, or July (all these have 31 days except April).
- A lectures on the 6th of a 31-day month, but not March (so, Jan or July).
- E immediately follows B (B, then E).
- Three lectures between A and B.
- Two persons between F and C; C is not last.
- The number after E equals the number before F (E in exact mid point from ends as F).
- G and C in same month.
- D is before H.
- To find: Who delivers on 6th March.
Trying all constraints one by one:
1. A delivers on 6th Jan or 6th July.
2. 3 persons between A and B ? e.g. A at 1, B at 5.
3. E follows B.
4. F and C–two between.
5. C not last.
6. G and C same month.
7. D before H.
Possible sequence by arranging constraints:
Let’s check the dates available:
- Jan: 6, 17
- Mar: 6, 17
- Apr: 6, 17
- July: 6, 17
A: 6 Jan or 6 July
If A is 6 Jan, then after 3 lectures: 17 Apr (A - _ - _ - _ - B), but let's check options.
After working through all constraints and careful sequencing,
B fits on 6 March.
So, the correct answer is:
Option 2: B
