Who among the following is DEFINITELY an expert in tabla but not in either mridangam or ghatam?
Explanation:
We can draw the following Venn diagram based on the information given in the main paragraph.
D is an expert in both tabla and ghatam. Since I is neither an expert in tabla nor in mridangam hence, he is an expert in ghatam ∴ D and I are the only two experts in ghatam.
Now, J is not an expert in tabla hence, he can only be an expert in mridangam only.
Also, H is not an expert in mridangam hence, he can only be an expert in tabla only.
Both A and B are experts in mridangam, but only one of them is also an expert in tabla. Both F and G are experts in tabla, but only one of them is also an expert in mridangam.
There are two experts in tabla and mridangam only one of them is either A or B and the other is either F or G.
∴ We can make the following Venn diagram
∴ H is an expert in tabla only.
Hence, option (c).
