An experiment measures quantities `a`, `b`, `c` and `x` the value of `x` is calculated from `x=ab//c^(3)`. If the maximum percentage error in `a`, `b` and `c` are `1%`, `1%` and `2%` respectively, then

Options

A. the error in `x` may be zero
B. for any particular reading, error in `x` may `10%`
C. maximum percentage error in `x` is `-4%`
D. maximum percentage error in `x` is `8%`

Explanation

`|(Deltax)/(x)|=|(Deltaa)/(a)|+|(Deltab)/(b)|+3|(Deltac)/(c )|`
