Four workers in Group A completed 20 jobs in March, which was four times the per capita quota of this month, while five workers in Group B completed 20 jobs, which was less than six times the per capita quota of this month.

If the actual per capita workload of the two groups of workers is the same this month, what is the per capita quota for this month?

Solution:

Let the per capita quota of this month be X, and there are:

(4x*4+20)/4=(5x*6-20)/5

x=4.5

If the per capita work actually completed by workers in Group A is 2 more than that in Group B, what is the per capita quota this month?

Let the per capita quota of this month be X, and there are:

(4x*4+20)/4=(5x*6-20)/5+2

x=3.5

If the workers in group A actually do 2 less jobs this month than those in group A, what is the per capita quota this month?

Let the per capita quota of this month be X, and there are:

(4x*4+20)/4=(5x*6-20)/5-2

x=5.5
