Find the value of $X$ in terms of $a$?
1. Arithmetic mean of $X$ and $Y$ is $‘a’$ while the geometric mean is also $‘a’$.
2. $X/Y = R; X - Y = D$.
- If any one of the statements alone is sufficient to answer the question.
- If both statements individually are sufficient to answer the question.
- If both statements together are required to answer the question.
