Given:
The ratio of present ages of Sushma and Karishma = 6 : 7
The ratio of their ages 8 years hence would be = 8 : 9
To find: The respective ratio of their ages after 12 years

Solution:
Let the present age of Sushma be 6x and Karishma be 7x.
After 8 years their ages will be (6x+8) and (7x+8) respectively
According to the question,
(6x+8)/(7x+8) = 8/9
54x+72 = 56x+64
2x = 8
x = 4
Present age of Sushma = 6x = 6*4 = 24
Present age of Karishma = 7x = 7*4 = 28

After 12 years,
Age of Sushma will be = 24+12 = 36
Age of Karishma will be = 28+12 = 40
Hence, the respective ratio of their ages after 12 years will be:
= 36/40
= 9/10
Therefore, the answer is option (c) 9:10.
