Question

A contractor estimates that 5 person can paint a house in 8 days. If he uses 6 persons, instead of 5, how long should they take to complete the job?

Answer 1

40/6 days

here when the number of persons increase then the no. of the days decrease so, a/q to question

x( no.  of the person)      y (no. of the days )

5                                         8

6                                         x

so inverse proportion formula is used because one value increases and the other decreases...

5 * 8=6 * x

or, 40=6x or, x=40/6
