Question

A line of length 1.5 metres was measured as 1.55 metres by mistake. what will be the value of error percent?

Answer 1

[1.55-1.5÷1.5]×100
[0.5÷1.5×100
10÷3
3 1÷3

Answer 2

Answer:

3.3%

Step-by-step explanation:

Actual length of line = 1.5 m

Measured Length = 1.55m

So, error % = $\frac{\text{Measured-Actual}}{Actual} \times 100$

                   = $\frac{1.55-1.5}{1.5} \times 100$

                   = $\frac{0.05}{1.5} \times 100$

                   = $0.033\times 100$

                   = $3.3\%$

Thus The value of error percent is 3.3%
