The population of a town increased from 1,62,500 to 2,62,500 in a decade. The average percent increase of population per year is : | [
"5%",
"8.75%",
"6.154%",
"4.37%"

Explanation:
Work done by P alone in one day = 1/6th of the total work done by Q alone in one day = 1/3(of that done by P in one day) = 1/3(1/6 of the total) = 1/18 of the total.
Work done by P and Q, working together in one day = 1/6 + 1/18 = 4/18 = 2/9 of the total
They would take 9/2 days = 4 (1/2) days to ... | AquaRat_train |
