Surendra, you have the same answer as the other tutor but I do not know what happened to you at the end and got something different, the term to the right is
((3/5)+(81/100)+(1/25) = (60/100)+(81/100)+(4/100) = 145/100
radius equal
√(145/100) = (√145)/10

Both answers are same.
 
Sqrt(29/20)=sqrt(145)/10
