Ankit gets a special drink made of from two different mixtures. First mixture of 150 ml contains 20% of alcohol. What volume (in ml) of another mixture containing 40% of alcohol must be mixed with the first mixture in order to obtain the special drink which contain 32% alcohol?
Explanation:
% Alcohol in the first mixture = 20% % Alcohol in the second mixture = 40%
By alligation rule,
The ratio of the two mixtures should be 2 : 3.
⇒ Q(Mixture 1)Q(Mixture 2) = 23
The quantity of the second mixture = 150 × 3/2 = 225 ml
Hence, 225.
