    Let number of old stuff = X and Total salary = N
    So, 8000 × X = N
    Now, two new members are recruited guard (Rs 5000) and manager (Rs 20000),
    Current staff = X + 2
    and Total salary = N + 20000 + 5000 = N + 25000
    Average new salary is 4000 more than the guard = 5000 + 4000 = Rs 9000
    So, 9000 × (X + 2) = N + 25000
    9000X = 7000 + N
    Substituting value of N from previous equation,
    9000X – 8000X = 7000
    X = 7000/1000 = 7
    Current staff = X + 2 = 7 + 2 = 9
