Sample Questions and Solutions
Part A: General Aptitude
1. A train travels 360 km in 6 hours. What is its average speed?
Solution:
Average speed = Total distance / Total time = 360 km / 6 hours = 60 km/h
Part B: Chemical Sciences
1. Which of the following is the strongest acid?
(a) HCl
(b) HBr
(c) HI
(d) HF
Solution:
The strength of an acid is determined by its ability to donate a proton. The bond strength between the hydrogen atom and the halogen atom decreases down the group. Therefore, HI is the strongest acid.
