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 $32$.
