Vedclass · Answer

(D) Let the number of other workers be $n$.Then,the number of agricultural workers is $11n$.Total income of agricultural workers $= 11n 	imes S = 11nS$.Total income of other workers $= n 	imes T = nT$.Total number of workers $= 11n + n = 12n$.Total income of all workers $= 11nS + nT = n(11S + T)$.Average annual income of all workers $= \frac{	ext{Total Income}}{	ext{Total Number of Workers}} = \frac{n(11S + T)}{12n} = \frac{11S + T}{12}$.

The average annual income (in $Rs.$) 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 annual income (in $Rs.$) of all the workers is
