SSC CHSL - 13 Nov 2025 - Shift 1 • Quantitative Aptitude • Q70

The diameter of a car's wheel is 63 cm. Calculate the distance the car travels when the wheel completes 1000 revolutions.

Show answer & explanation

Correct answer: A

Explanation

Diameter of the wheel = 63 cm
Number of revolutions = 1000
Circumference = πd
Distance covered in one revolution =π×63=227×63=22×9=198= \pi \times 63 = \frac{22}{7} \times 63 = 22 \times 9 = 198 cm
Distance covered in 1000 revolutions = 198 × 1000 = 198,000 cm
In kilometers = 198,000 / 100,000 = 1.98 km
