Answer:
9 years
Explanation:
let my age be 'x' years
Therefore,
Age of sister = x - 4 years
Age of brother = x + 3 years
Product of ages = 1872
x(x - 4)(x + 3) = 1872
or
x³ - x² - 12x - 1872 = 0
on solving the above cubic equation, we get
x = 13 as the only real root of the equation
Hence,
Age of the sister = x - 4
= 13 - 4
= 9 years
