Question

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?

• A. 12 years
• B. 15 years
• C. 19 and half
• D. 21 years

Answer 1

The correct option is B 15 years

Let the present ages of Arun and Deepak be 4x years and 3x years respectively. Then,
$4x+6=26\iff 4x=20$
$x=5$
$\therefore$ Deepak's age = 3x = 15 years
