i think that the ans will be 16%

smita96: yes

rajarshi02: then please tell how to approach to this answer

smita96: 2×2%+3×3%+1%+1/2×4%

smita96: by putting the p.Error of a b and c in the method

rajarshi02: so the division of the equation don't effect the answer.

rajarshi02: Thanks for helping

smita96: no no

smita96: i dont mean that

smita96: a2 b3/ c root d = 2 del a/a+ 3 del b/b + delc/ c + 1/2 del d / d

smita96: try this method
