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 20% lemonade syrup?
Choose one:
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 water70 L syrup.   To make 20% syrup solution, the result solution must have 120 L syrup and 30 L syrup.   Therefore we are taking 40 L of syrup from initial solution and replacing with water.   using urinary method:   70 L syrup in 150 L solution   40 L syrup in 85.7 L solution   We started by multiplying 10   Now to get to the result we need to divide by 40 =&gt; amount of solution to be replaced with water = (85.7/40) = 2.14.   2.14orrect option : 2.14
