Question

A jar contains a mixture of two liquids Acid (nitric acid) and Base (ammonium chloride) in the ratio 4 : 1. When 10 litres of the mixture is taken out and 10 litres of liquid Base is poured into the jar, the ratio becomes 2 : 3. How many litres of liquid Acid was contained in the jar?

Answer 1

Step-by-step explanation:

Explanation:

%age of liquid Base in the original mixture

=1/5 x 100 = 20%

In the final mixture % of the liquid Base

= 3/5 x 100 = 60%

Now using the rule of allegation

Hence reduced quantity of the first mixture and the quantity of mixture B which is to be added are the same.

Total mixture = 10 + 10 = 20 liters and quantity of liquid A = 20/5 x 4 = 16 lts
