    [SOLVED] Get original amount added by percentage

    Take 10% of 10. Result will be 1. Now add 1 in 10. Result will be 11.

    For example I have only amount 11 and 10% available. I want the original amount that is 10. How can I get this? Any formula?????

    For this we use cross-multiplication.

    You know that 11 = 100% + 10%

    So 11 = 110%
    And x = 100%

    \frac{11}{x} = \frac{110}{100}

    Solve for x
