The difficulty level of aptitude tests can vary based on the employer and the specific requirements of the fitter position. It is advisable to research the company and the role for which you are applying to gain a better understanding of the skills and knowledge they prioritize.

Q1. If a gear with 20 teeth is meshed with a gear with 40 teeth, how many times will the smaller gear rotate for every one rotation of the larger gear?
Ans. 
The smaller gear will rotate twice for every one rotation of the larger gear.
• The ratio of teeth between the two gears is 2:1 (40/20 = 2)

• For every one rotation of the larger gear, the smaller gear will rotate twice

• This is because the smaller gear has half the number of teeth compared to the larger gear
