Question

If a can do 1/3 of a work in 4 days and b can do 1/4 of the same work in 6 days, how much will a get if both work together and are paid rs.210 in all?

Answer 1

Answer:

rs 70

Step-by-step explanation:

A can finish 1/3 of work in 4 days

    4 = 1/3

     1 = 1/12

Similarly, B can do 1/4 of the same work in 6 days,

    6 = 1/4

     1 = 1/24

Ratio of work done A : B

     = 1/12 : 1/24

     = 1 : 2

Payment will be proportional to the work done and if both work together and are paid 210 then,

      By stating the ratios as fractions and cross multiplying

      1 / 3 = x / 210

      x = 210 / 3

      x = 70
