    Answer:

    The time will be “3 years“.

    Step-by-step explanation:

    The given values are:

    Principle,

    P = 5120

    Amount,

    A = 7290

    Rate,

    r = 12.5

    Time,

    n = ?

    As we know,

    ⇒  A = P[1+\frac{r}{100} ]n

    On substituting the values, we get

    ⇒  7290=5120[1+\frac{12.5}{100} ]n

    On applying cross-multiplication, we get

    ⇒  \frac{7290}{5120}=[1+\frac{125}{100}\times 100 ]n

    ⇒  \frac{9}{8}\times 3=[8+\frac{1}{8} ]n

    ⇒  n = 3 \ years
