    Answer:   10.5 cm

    =======================================================

    Explanation:

    25% = 25/100 = 0.25

    25% of 84 = 0.25*84 = 21

    So 21 cm has been cut off, leaving 84-21 = 63 cm left over

    Or you could say that if 25% has been cut off, then 75% of the stick remains

    So, 75% of 84 = 0.75*84 = 63 cm remains.

    The remaining length of 63 cm is cut into 6 equal pieces

    Each smaller piece is 63/6 = 10.5 cm long
