  1. The average monthly income (in ₹) of certain agricultural workers is S and that of other workers is T. The number of agricultural workers is 11 times that of other workers. Then, the average monthly income (in ₹) of all the workers is :
    1. S + 11T
      12
    2. S + T
      12
    3. 11S + T
      12
    4. 1
      12+ T
Correct Option: C

Let the number of other workers be n.
∴ Number of agricultural workers = 11n

∴ Required average monthly income = S × 11n + n × T
(11n + n)

Required average monthly income = ₹11S + T
12
