ट्रॅक्टरच्या मोठ्या व लहान चाकाचा व्यास अनुक्रमे 50 से.मी. व 35 से.मी. आहे. जेव्हा मोठ्या चाकाचे 21 फेरे पूर्ण होतील तेव्हा लहान चाकाचे किती फेरे पूर्ण होतील? The diameters of the bigger wheel and smaller wheel of a tractor are 50 cm and 35 cm respectively. How many revolutions will the smaller wheel make when the bigger one makes 21 revolutions ?
The distance covered by a wheel in one revolution is its circumference (π × diameter). Equate the total distance covered by both wheels: 50 × 21 = 35 × x, which gives x = 30.
