The Young's modulus (Y) of the material of a wire is given by `Y=(MgL)/(pir^(2)l)`.  The percentage errors in the load (Mg) suspended at the lower end, original length (L), radius (r ) and the extension (l) are 1%, 1.5%, 2% and 2.5% respectively. What is the maximum possible percentage error in Y?  [Take `g=10m//s^(2)`]
