Raj divided 50 into 2 parts such that the sum of their reciprocals is 1/12, we get the parts as
option
a) 36,14
b) 28,22
c) 20,30

• very simple 20,30
  we can cross check as-: 1/20+1/30=1/12

• let the 1st number be x then 2nd number will be 50-x
  (1/x)+(1/50-x)=1/12
  x2-50x+600=0
  solving we get x=20
  50-x=50-20=30

• 20, 30 is right ans
  u can go through options

• (1/x)+(1/50-x)=1/12;
  aftr solving we get,x=20,30;
  so in both cases....x=20,30

• Let the 1st number be x then 2nd number will be 50-x
  (1/x)+(1/50-x)=1/12
  (50x-x+x)/(x(50-x))=1/12
  12*50=50x-x^2
  x^2-50x+600=0
  solving we get x=20
  50-x=50-20=30
