Question

The density of a cube is measured by measuring its mass and length of its sides. If the maximum error in the measurement of mass and length are 4% and 3% respectively, the maximum error in the measurement of density will be
(a) 7%
(b) 9%
(c) 12%
(d) 13%

Answer 1

Here's your solution ,

Firstly.  ...We have asked all about density that is =

Mass/volume that is dimensionly( ML-3)

So %error in mass =3% and length=2% so by dimension , we have 

.....

M/M + 3L/L putting value of both we have …

3% + 3(2%)=9% is the ans
