Question from UPPSC Prelims CSAT 2024
The correct answer is: (C) 2, 4, 1, 3
Explanation:
To mend a puncture in a cycle tube, the steps should be followed in a logical sequence:
1. Step 2: First, remove the tyre and tube from the cycle and dip the tube in water to locate the puncture. The air escaping from the puncture will create bubbles, helping you identify the exact spot.
2. Step 4: Once the puncture is located, mark the spot and apply the puncture mending material (usually a rubber adhesive and a patch).
3. Step 1: Wait for the adhesive or material to dry properly to ensure a strong bond.
4. Step 3: Finally, fix the tyre and tube back onto the cycle.
