प्रश्न
Deepak is twice as old as his brother Vikas. If the difference between their ages is 11 years, find their present ages.
उत्तर
Let the present age of Vikas be x years.
Since Deepak is twice as old as Vikas, the present age of Deepak will be 2x years.
According to the question:
2x − x = 11
x = 11
∴ Present age of Vikas = 11 years
Present age of Deepak = 2x = 2××11
= 22 years
