Q: If a^{2x} = b^{3y} = c^{5z} and b = a^{2c}, then which one of the following is true?
(a)2/x + 3/y = 5/z
(b)1/x − 3/5z = 1/3y
(c)1/x + 1/5z = 1/3y
(d)2/x = 5/z = 3/y
Correct Answer: (c)
The correct answer is (c): 1/x + 1/5z = 1/3y. Subject: General Studies | Sub-topic: Miscellaneous Note: This answer was determined through AI-based research. Verify against the official answer key when available.
