1. The problem is to find the sum of all the group numbers filled in the table under the column "গ্রুপ নম্বর".
2. The group numbers given are: 2 (positions 1, 7, 14), 1 (position 3), 3 (positions 5, 6, 8, 13), 4 (positions 10, 12), 5 (position 15).
3. First, count how many times each group number appears:
- 2 appears 3 times
- 1 appears 1 time
- 3 appears 4 times
- 4 appears 2 times
- 5 appears 1 time
4. Calculate the sums for each group:
- Sum for group 2: $2 \times 3 = 6$
- Sum for group 1: $1 \times 1 = 1$
- Sum for group 3: $3 \times 4 = 12$
- Sum for group 4: $4 \times 2 = 8$
- Sum for group 5: $5 \times 1 = 5$
5. Add all these sums to get the total sum of group numbers:
$$6 + 1 + 12 + 8 + 5 = 32$$
6. Therefore, the total sum of the group numbers is $32$.
