x% people live 15 miles far from the office
y% people live 12 miles far from the office
(x+y) = 1
So the equation is
13 = (x%) x 15 + (1-x%) x 12
Solve for x and then you get x = 1/3 so y = 1 - 1/3 = 2/3.
So the ration will be (1/3) / (2/3) = 1/2

(x+y) = 1
So the equation is
13 = (x%) x 15 + (1-x%) x 12
Solve for x and then you get x = 1/3 so y = 1 - 1/3 = 2/3.
So the ration will be (1/3) / (2/3) = 1/2

Let,
No. of employees who live 12 miles away = x
No. of employees who live 15 miles away = y
Given,
(12x+15y)/(x+y) = 13
12x+15y = 13x+13y
2y = x
y/x = 1/2 (B)
Bunuel Shouldn't it be "what is the ratio of employees who live 15 miles away to those who live 12 miles away"?
