Answer» glass 1 has 2/3 of a glass alcohol and 1/3 of a glass water glass 2 has 1/2 of a glass of alcohol and 1/2 of a glass water. So the mixture in glass 3 (assuming it lage enough to contain the contents of both glass 1 and glass 2 and that glasses 1 and 2 are of equal volumes) has (2/3)+(1/2) of a glass of alcohol and (1/3)+(1/2) of a glass of water. So the ratio of alcohol to water in the mixture = ((2/3)+(1/2)) : ((1/3)+(1/2)) = 7/6 : 5/6= 7: 5 (b) is correct option |
