During a survey of company Y, Jay observes that the duration d, in which work gets completed in the company is inversely proportional to the sum of two quantities, the efficiency e of worker and the number of workerr,n. each of these two quantities is directly proportional to x.
It is also seen that e=1 n=10 and d=3 when x=2. Which of the following is a correct representation of d in terms of x?
A ) d = 3/{(x/2)+10}
B) d = 2x/{(1/2)+5x}
C) d = x/(x-5)
D) d = 6/x
E) d = 1/(1+x)
