If q workers can paint a house in d days, how many days will it take q+2 workers to paint the same house, assuming all workers paint at the same rate ? a. d+2b. d-2c. q+2 / qdd. qd / q+2e. (qd + 2d) / q

D.

Step-by-step explanation:

Given : q workers can paint a house in d days.

Let be the number of days taken by q+2 workers to paint the same house.

Since there is inverse relationship between the number of workers and the number of days to do same work ( condition - all workers paints at the same rate), as the number of workers increases the number of days to complete it decreases.

Equation of inverse variation between x and y  :

Substitute , and   , we get

Therefore , the number of days it will take  q+2 workers to paint the same house =

Hence, the correct answer is : D.

1; 35 is the ratio
