Question 1054351: In a business,Romeo and Juliet gained some amount in a certain ratio.Juliet and frank received the profits in the same ratio as Romeo and Juliet.if Romeo received $250 and frank received $360,what is the amount received by Juliet?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! let r = the amount that romeo gets.
let j = the amount that juliet gets.
let f = the amount that frank gets.
the ratio between romeo and juliet is r/j.
the ratio between juliet and frank is j/f.
these ratios are equal, so you get r/j = j/f.
if you want to find what juliet gets, you need to solve this equation for j.
multiply both sides of the equation by j and multiply both sides of the equation by f to get r * f = j * j
simplify to get r * f = j^2
solve for j to get j = plus or minus sqrt(r * f).
minus doesn't makes sense, so stick to j = plus sqrt (r * f).
since r = 250 and f = 360, this equation becomes j = sqrt (250 * 360).
solve for j to get j = 300.
that's your solution.
you now have the original ratios as 250/300 = 300/360.
simplify these fractions to get 5/6 = 5/6.
the ratios are the same.
the solution looks good.
the solution is that juliet gets 300.
