    D

    Step-by-step explanation:

    This basically means "7 is 5% of what number (total) ".

    We can directly translate this into algebra:

    Note: "is" means "equal" AND "of" means "multiplication". Also, let the total be n

    Let's write the equation.

    "7 is 5% of what number (total) "

    7 = 5% * n

    5% means 0.05, so:

    7 = 0.05 * n

    n = 7/0.05 = 140

    Total number of coins is 140

    Option D is right.
