Question : 34 of 150

Marks: +1, -0

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. Find the average monthly income (in Rs.) of all the workers:

${S+T}/2$
${S+11T}/2$
${1}/{11S}$ +T
${11S+T}/12$

Validate

Solution:

Let the number of other workers be x.
Then, number of agricultural workers = 11x
Total number of workers = 12x
∴ Average monthly income

= { { S } × 11 x + { T } × x } /{ 12 x } = { 11 { S } + { T } }/ { 12 }
