An experiment measures quantities x, y, z and then t is calculated from the data as t = 
. If percentage errors in x, y and z are respectively 1%, 3%, 2%, then maximum percentage error in t is :
Text Solution
Verified by ExpertsThe correct answer is:
D
t = 
= 
+ 
+ 
= 10 –2 + 2 × 3 × 10 –2 + 3 × 2 × 10 –2
= 13 × 10 –2
∴ % in t = 
× 100 = 13%
= 13 × 10 –2
∴ % = t = 
× 100 = 13%
