A number consists of two digits whose sum is 11. If 27 is added to the number, then the digits change their places. What is the number ?

A. 47 B. 65
C. 83 D. 92

• 47
  
  If number is xy , then x +y =11
  and
  10x+y +27 = 10y+x
  
  solving these eqns, we get
  x=4 and y =7
  
  so number is 47.
