Mixtures and Allegations Practice Test 1

In a 100 litre solution, 92 litre is acid. Now when water is added to the solution, acid content becomes 50%, but its quantity remains the same, i.e., 92 litres.
So, the water content must also be 92 litres, i.e., just 8 litre. So we need to add (92 - 8) litres of water, i.e., 84 litres of water.
