If a fixed group of letters must appear together in the same order, treat that entire group as one single block. Then count arrangements of the block + remaining letters. Short Solution Word BANGLORE has 8 distinct letters. The fixed string ANGLE uses 5 letters: A, N, G, L, E. Remaining letters: B, O, R (3 letters) So we have: - 1 block: ANGLE - 3 individual letters: B, O, R Total units to arrange =4 Number of permutations: 4!=24
