 let,    
     age of rakesh=x
     age of mohan=y
     age of shyam=z
given,
      x=10%y=10y/100=y/10(1)
      x=20z/100=z/5(2)
      substitute 1 in 2nd equation
therefore,we will get z/5=y/10
      z=y/2
therefore, shyam's age is twiceof mohan's age, that mean shyam's age is 200% of mohan's age.
