The sum of two numbers is 2016 and their product is 32 the sum of their reciprocals is

• X+y=2016
  xy=32
  1/x+1/y=x+y/xy=2016/32
  =63

• let two no are x,y
  x+y=2016 ......(1)
  xy=32 ......(2)
  
  therefore
  1/x+1/y=x+y/xy=2016/32=63

• Given a+b=2016 ab=32
  we Know that (a+b)^2 -(a-b)^2 =4ab substitute a+b &ab in the equation you get a-b.
  solve a+b &a-b you get a=2015.984 &b=0.016 and take reciprocal of these numbers you get 62.50049 which is approximately equal to 63 in the option
