An interview panel found that a candidate has given a wrong date about his height .while filling up his form he filled up 20% more than his actual height .his actual height is 5 feet 2 inches.By what approximate percent should he reduce his height to get actual height?

a)15
b)14
c)18
d)17

• d) 17
  
  If actual height= x feet
  With 20% increase, new height=x*120/100=1.2x
  So percentage reduction needed=100*(1.2x -0.2x)/1.2x=16.66 ~17

• use formula- (r*100)/(100+r)
  
  (20/120)*100 % = 16.66 =17%
