Question

) A number 3-625 is wrongly read as 3-266
find the percentage error.​

Answer 1

Step-by-step explanation:

) Correct number = 3.625

Number wrongly read as = 3. 265

Error = 3. 625 – 3. 265

= 0.360

% Error = 0.360/3.625 × 100

= 360/3625 × 100 = 36000/3625 = 9.93%

(ii) Correct number = 5.78 × 103

Number wrongly written as = 5. 87 × 103

Error = 5.87 × 103 – 5.78 × 103

= 0.09 × 103

% Error = (0.09 × 103)/5.78 × 103 × 100

= 0.09/5.78 × 100 = 9/578 × 100 = 900/578 %

= 1.56%
