(3) (xa - yb + zc)% (4) (xa - yb – zc)%​

Answer 1

Explanation:

A physical quantity 'Y is represented by formula

ABY

Y Y =

If maximum possible percentage

CZ

errors in A, B and C respectively are a%, b% and

c% then final maximum possible error is

(1) (xa + yb + zc)% (2) (xa + yb - zc)%

(3) (xa - yb + zc)% (4) (xa - yb – zc)%
