Question

If x = a – b, then the maximum percentage error in the measurement of x will be
(a) $\bigg \lgroup \frac{\triangle a}{a} + \frac{\triangle b}{b}\bigg \rgroup \times 100$%(b) $\bigg \lgroup\frac{\triangle a}{a} - \frac{\triangle b}{b}\bigg \rgroup \times 100$%
(c) $\bigg \lgroup \frac{\triangle a}{a-b} + \frac{\triangle b}{a-b}\bigg \rgroup \times 100$%(d) $\bigg \lgroup \frac{\triangle a}{a-b} - \frac{\triangle b}{a-b}\bigg \rgroup \times 100$%
