At present, the ratio between the ages of Arun and Deepak is 4 : 3. After 6 years, Arun's age will be 26 years. What is the age of Deepak at present ?
Answer: B
Let the present ages of Arun and Deepak be \(4x\) years and \(3x\) years respectively . Then ,
\(4x+6=26\)
\( \Rightarrow 4x=20\)
\(\therefore x=5\)
Now, Deepak's age = \(3x\) = 15
