    Answer: (3) 81 cm
    Explanation:-
    The height of a tree = 64 cm
    Tree increased annually by 1/8th
    Then,  the height of tree after one year = 64 + 64 x 1/8
    = 64 + 8
    = 72 cm.
    The height of tree after two year = 72 + 72 x 1/8′
    = 72 + 9
    = 81 cm
    Hence, the height of tree after two years will be 81 cm.
