    Explanation:
    Let the age of A be x years and age of B be y years,
    A.T.Q,
    =\frac{A+2}{B}=\frac{5}{6}
    6A + 12 = 5B
    6A – 5B = - 12 ---------- (i)
    \frac{A+8}{B+6}=\frac{6}{7}
    7A + 56 = 6B + 36
    7A – 6B = - 20 ----------- (ii)
    On solving eq. (i) and (ii), we get
    A = 28 and B = 36
