Question 9

In a mixture of 35 litres, the ratio of water and acid is 6 : 1. If 5 litres of acid is added to the mixture, then what will be the ratio of water and acid in the new mixture?

Solution

Total quantity of mixture = 35 litres and ratio of water and acid is 6 : 1

=> Quantity of water = $$\frac{6}{(6+1)}\times35=30$$ litres

Thus, quantity of acid = $$35-30=5$$ litres

Now 5 litres of acid is added to the mixture, => acid = $$5+5=10$$ litres

=> Ratio of water and acid in the new mixture = $$\frac{30}{10}=3:1$$

=> Ans - (C)
