Answer 2

The average monthly income would be Rs. 1134.11.

Step-by-step explanation:

Since we have given that

Average annual income of 11 workers = Rs. 14650

Average annual income of 2 workers = Rs. 19333

We need to find the average monthly income for remaining 9 workers.

So, we will first find yearly average income for 9 workers.

According to question, it becomes,

$\dfrac{\sum x}{11}=14650\\\\\dfrac{x_1+x_2+\sum_{x=3}^{11}}{11}=14650\\\\19333\times 2+\sum _{x=3}^{11}=14650\times 11\\\\\text{Sum of incomes of Remaining 9 workers }=161150-38666=122484\\\\\text{Average of remaining 9 workers}=\dfrac{122484}{9}=13609.33\\\\\text{Average monthly income of 9 workers }=\dfrac{13609.33}{12}=1134.11$

Hence, the average monthly income would be Rs. 1134.11.
