15 persons finished the work in 30 days.

persons required to finish the same work in 45 days..

By applying the ratio of proportionality,

x/15 = 30/45

x= (30*15) / 45

no.of.persons required = 10 persons.

12abhi: can u explain chain rule.plz

Aishwarya98: if the no.of.days increases, the no.of.person decreases..
