is it 10%
relative density of a material is found by ratio of weight in air and decrease in weight in water. If weight of a body in air and water are measured as W in air = (10.0+-0.4)g and W in water = (5.0 +- 0.1)g, then percentage error in relative density will be??

find out relative error in each measurement and then multiply by 100 to find %error

the question should be worded as
then max percentage error in relative density will be??
otherwise... all answers are false..
it can be anything between ±the max % error
