Slot – 1 – Quantitative Aptitude – Ratio and Proportion – A solution, of volume 40 litres, has dye and water


Q. A solution, of volume 40 litres, has dye and water in the proportion 2 : 3. Water is added to the solution to change this proportion to 2 : 5. If one-fourths of this diluted solution is taken out, how many litres of dye must be added to the remaining solution to bring the proportion back to 2 : 3?
Answer: 8

Solutions:
Solution 1= 40 L (Dye=16L , Water=24L)
Solution 2 (Adding water)
Qtty. of dye = 2x=16 ->x=8
Qtty. of water = 5x =40
Total Vol. Solution2=56L
ΒΌ of solution = 56/4= 14L
Remaining Solution 56-14= 42L
