An experiment measures quantities a,b,c and d and x is calculated from formula
`x=(ab^(1//2))/(c^(3//2)d^(3))`.
The percentage errors in a,b,c and d are `2%`, `4%` `, 6%` and `1%` respectively. What is the percentage error in x ?

P= A^3. B^(1/2) . C^1 . If percentage errors in A, B and C are 1, 2 and 4 respectively, then find the percentage error in P.

A physical quantity X is related to four measurable quantities a, b, c and d as follows. X = a^2 b^3 c^(5//2) d^-2 The percentage error in the measurement of a,b,c and d are 1%,2%, 3% and 4%, respectively. What is the perecentage error in quantity X? If the value of X calculated on the bais of the above relation is 2.7 63, to what value should you round off the result?

A physical quantity P is related to four observables a, b, c and d as follows :- P=a^3b^2//((sqrtc)d) The percentage errors of measurement in a, b, c and d are 1%, 3%, 4% and 2%, respectively. What is the percentage error in the quantity P? If the value of Pcalculated using the above relation turns out to be 3.763, to what value should you round off the result ?

A physical quantity 'x' is given by the relation x=(a^(2)b)/(sqrt(c )) If errors in a, b and c are 2% and 3% and 4% respectively, calculate percentage error in 'x'.

If a physical quntity is P = (a^3 b^2)/c and the percentage errors in the measurement of a,b and c are 1%,2% and 3% respectively.Find the maximum percentage error in the measurement of physical quantity P.

If the error in the measurement of radius of a sphere is 3%,then what will be the percentage error in the volume of the sphere?

In a tape recorder factory, three machines A, B and C produced 50%, 30% and 20% of total production. The percentage of the defective output of these machines are 3%, 4% and 5% respectively. A tape recorder is selected randomly and found to be defective, find the probability that it is produced by machine A.
