60 is to be divided into two parts such that the sum of 10 times the first and 22 times the second is 780. The bigger part is :	Pick:	A) 33	B) 45	C) 26	D) 28	E) 19

Rationale: "explanation : let the two parts be ( 60 - x ) and x . then , 10 ( 60 - x ) + 22 x = 780 = > 12 x = 180 = > x = 15 . bigger part = ( 60 - x ) = 45 . answer : b ) 45"
Answer: B
