    After A increases by 25%, it equals B. What percentage of B is the original

    value of A??

    A(1+25%)=B

    A=B//(125%)

    A=0.8B

    therefore, 80% of B is the original value of A.

    value of A??

    A(1+25%)=B

    Percentage of B is the original value of A

    = B/A *100%

    = 1.25A/A *100%

    = 1.25 *100%

    = 125%
