Problema Solution
in what ratio should a grocer mix tea at rs3.10/-per kg with tea at rs4.35/-per kg to make a mixture worth rs3.25/-per kg
Answer provided by our tutors
let
x = kg of the tea at rs3.10/-per kg
y = kg of the tea at rs4.35/-per kg
we need to find x/y
3.10x + 4.35y = (x + y)3.25 divide both sides by y
3.10(x/y) + 4.35 = (x/y + 1)3.25
let t = x/y
by solving the equation:
3.10t + 4.35 = (t + 1)3.25
we find:
t = 22/3
click here to see the step by step solution of the equation:
x/y = 22/3
the ratio of the tea at rs3.10/-per kg to tea at rs4.35/-per kg should be 22 to 3.
