Directions: The line graph given below shows the percentage concentration of two liquids (X and Y) in five mixtures A, B, C, D and E. It also contains a table that gives the concentration of liquid Z (in litres) in all these mixtures. (Note - The mixtures are made up of only these three liquids)
Find the ratio of quantity of liquid Z in mixture A and B combined to the sum of quantities of X in liquid C and Y in liquid D.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 1125 : 518
Z in A and B combined = 81 + 144 = 225 litres
Percentage concentration of Z in mixture C = 100 - (42 + 33) = 25%
25% of Total Volume = 20
Total volume (C) = 80 litres
Concentration of X = 42% of 80 = 33.6 litres
Percentage concentration of Z in mixture D = 100 - (30 + 28) = 42%
42% of Total Volume = 105
Total volume (D) = 250 litres
Concentration of Y = 28% of 250 = 70 litres
Sum = 70 + 33.6 = 103.6
Ratio = 225 : 103.6 = 1125 : 518
