In an experiment four quantities a,b,c and d are measure with percentage error `1% , 2% , 3%`,and `4%` respectively quantity is P is calculate as follow `P = (a^(3)b^(2))/(cd) %` error in `P` isA. `14%`B. `10%`C. `7%`D. `4%`

Answer» Correct Answer - A
`P=(a^(3)b^(2))/(cd)`
Error in `((DeltaP)/(P))=3((Deltaa)/(a))+2((Deltab)/(b))+((Deltac)/(c))+((Deltad)/(d))`
`=3(1%)+2(2%)+3%+4%=14%`
