Given, the ratio of Ram and Shyam's ages = 2:1
Let Ram's age be 2x and Shyam's age be x.

After 5 years, the ratio of their ages = 3:2
So, (2x+5)/(x+5) = 3/2
Cross-multiplying, we get 4x+20 = 3x+15
Solving the above equation, we get x=5.

Therefore, Ram's age = 2x = 2*5 = 10
And Shyam's age = x = 5

Hence, the correct answer is option B) 10 and 5.
