      Solution

      ATQ;
      Let the monthly savings of A, B, and C be Rs. ‘9x’, Rs. ‘10x’, and Rs. ‘12x’, respectively.
      So,
      Monthly income of A = (9x/0.25) = Rs. ‘36x’
      Monthly income of B = (10x/0.3) = Rs. ‘33.33x’
      Monthly income of C = (12x/0.35) = Rs. ‘34.29x’
      ATQ;
      (36x + 33.33x + 34.29x) = 88800
      Or, 103.62x = 88800
      So, x = 856.9
      Therefore, monthly salary of 'C' = 34.29x = 34.29 × 856.9 = Rs. 29,399
