Question. 84
Correct length = 19.33 cm. Errors made:
Ravi = 19.34 cm, Kamal = 19.25 cm, Tabish = 19.27 cm.
Answer:
Ravi +0.01 cm, Kamal −0.08 cm, Tabish −0.06 cm
Detailed Answer with Explanation:
Error = Measured – Correct. Ravi: 19.34 − 19.33 = +0.01. Kamal: 19.25 − 19.33 = −0.08. Tabish: 19.27 − 19.33 = −0.06.
