Correct answer: B
Revolutions by a wheel = Distance covered / Circumference
Circumference of wheel = Perimeter of wheel
Revolutions by front wheel = (Distance covered / Circumference of front wheel)
240 =Distance / 30
Distance = 7200
Revolutions by back wheel = (Distance covered / Circumference of back wheel)
Revolutions = 7200 / 20 = 360
Hence Option (B)
