Question

the ratio of the number of male and female workers in textile mill is 5:3 . If there are 115 male worker , what is the number of female workers in the mill.

Answer 1

Ratio:5:3
Male:115
Female:(115÷5)×3=69

Answer 2

let the number of female workers be X .
according to the question:-
5:3::115:X
product of extremes = product of means
5 × X = 115 × 3
5x = 345
X = 345/5
X = 69
hence there are 69 female workers in the mill
