No need guess n check.
Assume all 20 vehicles have 2 wheels.
If so no. of wheels = 40
But actual is 62.
Therefore difference = 62 - 40 = 22
Each car is suppose to haf 4 and not 2 wheels as previously assumed ie each car suppose to haf 2 MORE wheels.
Therefore the 22 'extras' must be from the cars. Since e cars r supposed to haf 2 MORE wheels EACH, no. of cars =22/2 = 11. So motorcycles 9, cars 11.
