Question 22

The first quality of juice costs Rs.15 per litre and the second quality of juice costs Rs.10 per litre. If the mixture of these two qualities is sold at the rate of Rs.14 per litre, then the ratio in which these two qualities of juices are to be mixed in order to get a profit of 20% is

Solution

Let say, he mixed x of first quality with y of second quality.

Ao,price of x amount of first quality is 15x.

and price of y amount of second quality is 10y.

but he sold (x+y) in 14(x+y).

So,

(15x+10y)1.2=14(x+y)

or,18x+12y=14x+14y.

or,4x=2y.

or,2x=y.

So, x/y=1/2=(1/2)/1.

so,x:y=(1/2):1.

C is correct choice.
