Question

in what variety three ways of coffee 1 rupees 26 per kg and other 40% kg in the third 400 per kg should be mixed together with Pradesh variety of coffee with 340 per kg​

Answer 1

Answer:

Since first and second varieties are mixed in equal proportions so their average price 

=(2126+135)=Rs.130.50

So, the mixture is formed by mixing two varieties one at Rs.130.50 per kg 

And the other at say Rs.x per kg in the ratio 2:2 i.e. 1:1.

We have to find x.

By the rule of alligation, we have 

1=22.5x−153153+22.5=x

⇒x=Rs.175.50
