Yes the answer is 100.
Root of (0.0169*x) = 1.3.
Root of (169/10000*x) = 1.3.
13/100*(root of x) = 1.3.
Root of x = 1.3*(100/13).
Root of x = 10.
So finally x= square of 10 which is 100.
Root of (0.0169*x) = 1.3.
Root of (169/10000*x) = 1.3.
13/100*(root of x) = 1.3.
Root of x = 1.3*(100/13).
Root of x = 10.
So finally x= square of 10 which is 100.
