If the centre distance between a pair of spur gears in mesh is 240 mm and the pinion moves five times faster than the gear, then the pitch circle diameters of pinion and gear respectively are

If the centre distance between a pair of spur gears in mesh is 240 mm and the pinion moves five times faster than the gear, then the pitch circle diameters of pinion and gear respectively are Correct Answer 80mm and 400 mm

rp + rg = 240 rp/rg = 5 rg = 200 mm, dg = 400 mm rp = 40 mm, dp = 80 mm.
