A physical quantity P is described by the relation P= a^1/2 b^2 c^3 d^-4 . If the relative error in the measurement of a,b,c and d respectively are 2% , 1%, 3%, 5% then the relative error in P will be? (a) 8% (b) 12% (c) 32% (d) 25%

Dear Student,
                    Given formula is                     P=a12b2c3d-4-------1   for maximum error in P   PP×100=12aa×100+2bb×100+3cc×100+4dd×100                         =12×2+2×1+3×3+4×5=3200
option c is correct
