Perimeter of front wheel =30, back wheel = 20. If front wheel revolves 240 times. How many revolutions will the back wheel take?

• sice the distance covered by both the wheels should be same
  so
  let x be the no. of revolutions by the back wheel
  so 240*2*pie*30=x*2*pie*20
  so x=360.

• Assume revolution of back wheel is X and here 240*30=7200 so 20*X=7200 and X=360..
  so 360 is answer...

• revolution of back wheel is X
  therefore 240*30=x*20
  7200 =20x
  x= 360
  so the answer is 360
