Two years ago from now, age of 'A' was ____ years. Ratio of present ages of 'A' and 'B' is ____ respectively and four years hence from now, sum of ages of 'A' and 'B' will be ____ years. The data given in which among the given options will fill the blank in the same order so as to make the statement true?
I. 19, 3:4, 70
II. 16, 2:3, 53
III. 23, 5:7, 68

Statement I:
Present age of 'A' = 19 + 2 = 21 years
Present age of 'B' = (4/3) × 21 = 28 years
Required sum = 21 + 4 + 28 + 4 = 57 years
So, statement I is not true. Statement II:
Present age of 'A' = 16 + 2 = 18 years
Present age of 'B' = (3/2) × 18 = 27 years
Required sum = 18 + 4 + 27 + 4 = 53 years
So, statement II is true. Statement III:
Present age of 'A' = 23 + 2 = 25 years
Present age of 'B' = (7/5) × 25 = 35 years
Required sum = 25 + 4 + 35 + 4 = 68 years
So, statement III is true. Therefore, both statements II and III are true. Hence, option C .
