Related Solution A and solution B are 2 solutions of orange such that the concentration of orange juice is 64% in solution A and the concentration of water is 20% in solution B. Solution A and B are mixed in a ratio x:y such they form a 20 liter solution which has 6 litres of water. What is the value of 3x+2y if it is known that xand yare co-prime?a)5b)9c)19d)21Correct answer is option 'D'. Can you explain this answer?
The concentration of orange juice in solution A = 64%
The concentration of orange juice in solution B = 100-20 = 80%
The resultant solution obtained by mixing is of volume 20L out of which 6 L is water.
Quantity of orange juice = 20L - 6L =14L
Concentration of orange = 14/20 ​× 100% = 70%
As per question 0.64x + 0.8y = 0.7(x+y)
0.1y = 0.06x
x​/y = 0.1​/0.06 = 35​
x = 5 and y = 3
3x + 2y = 3(5) + 2(3) = 15 + 6 = 21

Orange percentages :A : 64%B : 80% ( water % is given in question )Mixture : 70% ( from question 6L in 20L means 30% water ) Now A. B. 64. 80 70. 10. 6. = 10:6 = 5:3 ; x=5,Y=3 substitute in equation. Will get 21.
