III. The difference between the present ages of Rohit and his son is 27 years. Correct Answer All statements are required

Statement I:

The age of Rohit at the time of marriage = 25 years.

Statement I alone is not sufficient to answer the question.

Statement II:

Total age of Rohit and his wife at the time of marriage = 24 × 2 = 48 years.

Statement II alone is not sufficient to answer the question.

Statement III:

Difference between the ages of Rohit and his son = 27 years

Statement III alone is not sufficient to answer the question.

Statement I + Statement II + Statement III;

I) The age of Rohit at the time of marrige = 25 years

II) The age of Rohit’s wife at the time of marriage = 48 – 25 = 23 years

III) Difference between the present ages of Rohit and his son = 27 years

∴ Son should have born after 2 years of marriage.

∴ Difference of ages of Rohit’s wife and his son = 23 + 2 = 25 years

Hence all the statements are required to give the answer
