A mixture of 70 litres of Fruit Juice and water contains 10% water. How many litres of water should be added to the mixture so that the mixture contains 12.5% water?
2.5 ltrs
Incorrect AnswerExplanation:
Quantity of fruit juice in the mixture = 70 - [70 x (10/100) ]= 63 litres.
After adding water, juice would form 87.5% of the mixture.
If quantity of mixture after adding x liters of water, [(87.5) /100 ]*x = 63 => x = 72
72 - 70 = 2 litres of water must be added.
Hence, option 1 is the correct answer.
