Question

mixing 2 varieties of X and Y of cofee in the ratio 2.5 what percentage of the mixture is type Y​

Answer 1

Answer:

Consider the amount of pulse of price Rs15 =x

And the amount of pulse of price Rs20 =y

Then the total amount of mixture =15x+20y

But the price per kg of mixture =Rs16.50

So, total price of x+ykg =16.50(x+y)

Now according to the equation

16.50(x+y)=15x+20y

16.50x+16.50y=15x+20y

1.50x=3.50y
