Question :- 5 person complete a certain job in 2 days how many days will 10 persons take to finish the job
Numbers of persons ∝ 1/ Time taken to
complete
If number of persons double, time will be halved.
Here, 5 persons -----> 2 days.
10 persons -----> x days.
We know that x ∝1/y => x1 * y1 = x2 * y2
5*2 =10* x
x = 1 day.
Hence, 10 persons take 1 day.
