Question

The relative error in 'P' =?

Answer 1

`C) 32%`

Explanation:

given, `P=a^(1/2) b^2 c^3 d^(-4)`

So,we can say, relative error in calculation of `P` is,

`(delta P)/P = 1/2 (delta a)/a + 2 (delta b)/b + 3 (delta c)/c +4 (delta d)/d`

Putting the given values of percentage error of `a,b,c,d` in the equation,we get,

`(delta P)/P *100=(1/2 *2) +(2*1)+(3*3) +(4*5)=32`
