Correct Answer - Option 2 : 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.)
