Correct Answer

Explanation

By letting the age of Minu be represented by 4X and the age of Meera be represented by 2X,
you were able to set up the equation 4X + 2X = 6,
which represents the statement "the sum of their ages is 6 years." 
Solving this equation for X gives you X = 1,
which means that Minu is currently 4 years old and Meera is currently 2 years old.  
 
You then correctly found the ratio of their ages after 8 years by adding 8 to both of their
current ages and expressing the result as a ratio: (4+8):(2+8) = 12:10 = 6:5.
