A solution contains 8 parts of water for every 7 parts of Lemonade syrup. How many parts of the solution should be removed and replaced with water so that the solution will now contain 40% lemonade syrup?
Answers:
A) 1.5
B) 1.75
C) 2.14
D) 2.34
E) 2.64
Let the total solution is 150 L with 80 L water &amp; 70 L syrup.   To make 40% syrup solution, the result solution must have 90 L syrup and 60 L syrup.   Therefore we are taking 10 L of syrup from initial solution and replacing with water.   using urinary method:   70 L syrup in 150 L solution   10 L syrup in 21.4 L solution   We started by multiplying 10   Now to get to the result we need to divide by 10 =&gt; amount of solution to be replaced with water = (21.4/10) = 2.14.   2.14orrect option : 2.14
