Q10.Two persons could fit new windows in a house in 3 days.

(i) One of the persons fell ill before the work started. How long would the job take now?

Answers (1)

Here, given that 2 persons could fit new windows in a house in 3 days.

(i) 1 person has fallen ill so, now the number of persons remaining is only one. Assume that the only person which is working takes the time of 'x' days.

hence we could write the inverse relation as;

2persons\times 3 days = 1 person\times x days

or       x= 6days.

One person will take 6 days to complete that window job.
