The price of two kinds of juices is Rs. 28 per kg and Rs. 56 per kg respectively. Both the juices are mixed in the ratio 4 : 9. Find the price of mixed juice per kg (to the neatest whole number)?  Correct Answer 47

Given:

The price of two kinds of juices is Rs. 28 per kg and Rs. 56 per kg respectively. Both the juices are mixed in the ratio 4 : 9. 

Formula:

Average marks = Total marks of all the students/total number of students

Calculation:

Let the cost of mixed juice be Rs. x

As per the alligation rule,

4 : 9 = (56 - x) : (x - 28)

⇒ 4x - 112 = 504 - 9x

⇒ 13x = 616

⇒ x = 47.38 ≈ 47

The Price of mixed fruit per kg is Rs. 47(approx.)
