A number whose fifth part increased by 5 is equal to its fourth part diminished by 5 is ?	Choose the correct choice from the following answers
A) 160	B) 180	C) 200	D) 220	E) None
Answer   Let the number be N.   Then, (N/5) + 5 = (N/4) - 5   ⇒ (N/4) - (N/5) = 10   ⇒ (5N - 4N)/20 = 10   ∴ N = 200   Option: 200
