The Correct Option is A
Solution and Explanation
We can solve this problem using only statement A.
Let Shruti's current age be 14x and Aditi's current age be 11x.
After 6 years:
- Shruti's age will be 14x + 6
- Aditi's age will be 11x + 6
According to statement A, the ratio of their ages after 6 years will be 17:14
So, \(\frac{(14x + 6) }{ (11x + 6) }= \frac{17 }{ 14}\)
Cross-multiplying, we get:
14(14x + 6) = 17(11x + 6)
196x + 84 = 187x + 102
9x = 18
x = 2
Therefore, Shruti's current age is 14x = 14 \(\times\) 2 = 28
Final Answer: The statement A alone is sufficient to answer the question, but the statement B alone is not sufficient.
So the correct option is (A)
