    \Large \fbox \red {Question \: :}

    A number when decreased by 10 % gives 45. What is the number?

    \Large \fbox \red {Answer \: :}

    \implies Let the number be x.

    x \: - \: 10\% \: of \: x \: = \: 45

    x \: - \: \frac{x}{10} = 45

    \frac{9x}{10} = 45

    9x = 450

    x = \frac{450}{9}

    x = 50

    \therefore The number is 50.

    Let x = the number

    Then, x – 0.10x = 45

    0.90x = 45

    x = 50
