1.	If,R=a^2√b/c^4d and percentage error in measurement of a,b,c and d are 0.1%,0.2% ,0.3% and 0.4% respectively ,then the maximum percentage error in R is (a) 1.9% (b) 3.1% (c) 2.9% (d)4.0%
Answer» The Percentage error is 1.9 %Given:Error % in a = 0.1 %Error % in B = 0.2 %Error % in c = 0.3 %Error % in d = 0.4 %Explanation:Given equation is,THEREFORE, For finding the percentage error,Now, For percentage we NEED to MULTIPLY it with 100.Substituting the values,∴ The Percentage error is 1.9 %.Hence, 1ST Option is correct !
