Option 4 : Either statement III alone or statement I and II together are sufficient to answer the question.
Statement III:
Difference between the present ages of the Mamta and Barkha is 26 years;
Since the ratio between the present ages of the Barkha and Mamta is 1 : 3;
∴ Present age of Mamta = × 3 = 39 years
Statement I and II:
Neha - Barkha = 22 and
Neha = 3 × Barkha - 4
We can find the age of Barkha then with the help ratio of ages of Barkha and Mamta, we can find the age of Mamta too.
∴ Either statement III alone or statement I and II together are sufficient to answer the question.
