The age of a person is thrice the total ages of his 2 daughters. 0.5 decades hence, his age will be twice of the total ages of his daughters. Then what is the father’s current age? [0.5 Decades = 5 Years]
Answer: C
Let, Total of current ages of the 2 daughters is \(A\) years.
Then, father’s current age = 3A years.
\((3A + 5) = 2 (A +10)\)
\(\Rightarrow\) \(3A + 5 = 2A + 20\)
\(\Rightarrow A = 15\)
Therefore, father’s current age = 45 years.
