Question

The ratio of Vimal’s age and Arun’s age is 3:5 and sum of their ages is 80 years. The ratio of their ages after 10 years will be

• A. 3:2
• B. 2:1
• C. 1:2
• D. 2:3

Answer 1

The correct option is D 2:3

Let the age of the Vimal and Arun be 3x, 5x resp.
From the given condition, we get
$3x+5x=80\Rightarrow 8x=80\Rightarrow x=\frac{80}{8}=10Then,Vima{l}^{\prime }sageis3x=3\times 10=30andAru{n}^{\prime }sageis5x=5\times 10=50$
After ten years, Vimal's age will be 30 + 10 = 40
Arun’s age will be 50 + 10 = 60
Then their ratio = 40 : 60 = 2 : 3
