# the forewheel of tractor makes 120 revolution more than the rear wheel in going 720m. if the diameter of the forewheel is doubled and the diameter of the rear wheel in increased by half times the present diameter then the forewheel makes 20 revolution more than the rear wheel in going the same distance find the circumference of each wheel

Expert Answer:

### Let the front wheel diameter = d_{1}
Rear wheel diameter = d_{2}
By the given conditions
Solving (1) and (2) simultaneously, we get d_{1} and d_{2}
d_{1} = -320/pi and d_{2} = 440/pi
d_{1} = -1120/11 and d_{2} = -140

_{1}

_{2}

_{1}and d

_{2}

_{1}= -320/pi and d

_{2}= 440/pi

_{1}= -1120/11 and d

_{2}= -140
