Given,
3(log 5 - log 3) - (log 5 - 2log 6) = 2 - log n
⇒ 3log 5 - 3log 3 - log 5 + 2log 6 = 2 - log n
⇒ 2log 5 - log 33 + log 62 = 2 - log n
⇒ log 52 - log 27 + log 36 = 2 - log n
⇒ log 25 - log 27 + log 36 = 2log 10 - log n
⇒ log = log 102 - log n
⇒ log = log 100 - log n
⇒ log 100 - log 3 = log 100 - log n
⇒ log n = log 3
⇒ n = 3.
Hence, n = 3.
