Question

Ratio of two quantities a and b is 7:8.if two quantities are mixed,then the percentage of a in the mixture is

Answer 1

Here is the solution :

Let the highest common divisor be x,

=> a = 7x, and
=> b = 8x,

Total quantity = a+b = 15x,

Percentage of a =
(Quantity of a in mixture)/(Total Quantity of Mixture) *100,

=> Percentage of a in mixture = (7x)/(15x) *100,
=> Percentage of a in mixture = 7/15*100 = 46.6666,

Therefore : Percentage of a in the mixture = 7/15% or 46.67%(Approx),
