Suppose the correct barometer height at O°C is -l0, then
l0 + Δl = 75
or l0 + 75 x (αHg - αb) x 27 = 75
or
l0 + 75 x (0.6 x 10-4 - 0.2 x 10-4) x 27 = 75
∴ l0 = 74.92 cm
l0 + Δl = 75
or l0 + 75 x (αHg - αb) x 27 = 75
or
l0 + 75 x (0.6 x 10-4 - 0.2 x 10-4) x 27 = 75
∴ l0 = 74.92 cm

The statement is incomplete and does not provide enough information to determine the accuracy of the brass scale of the barometer. The accuracy of a barometer scale depends on various factors such as calibration, design, and manufacturing quality. Additionally, the statement does not specify what the correct reading at 0 refers to, whether it is atmospheric pressure or another measurement.
