54 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	Select:
A) 24  B) 30  C) 32  D) 34  E) 36
Solution   Let the two parts be (54 - x) and x.   Then, 10(54-x)+22x=780   = 12x = 240   ‹=›x = 20.   Therefore Bigger part = (54-x) = 34.   Answer 34
