Diameter of the front wheel and hind wheel of a van are 70 cm and 98 cm respectively. How many more revolutions the front wheel will make when the hind wheel in going over a distance of 154 kms?

A) 10000
B) 15000
C) 20000
D) 25000

Correct Answer:



C) 20000

Description for Correct answer:

\( \Large n_{1}c_{1}=154 km \)

\( \Large n_{1} \times \frac{22}{7} \times 98 cm = 15400000 cm \)

\( \Large n_{1}=70000 \)

\( \Large and \ n_{1}c_{2}=154 km \)

\( \Large n_{2} \times \frac{22}{7} \times 98 cm = 154000000 cm \)

\( \Large n_{2} = 50000 \)

\( \Large n_{1} - n_{2} = 20000 \)
