Last Minute Prep Quiz for OSSSC RI, ARI, AMIN: 04 October 2024
- A boat can travel at 12 km/h in still water. If it takes the boat 3 hours to travel 36 km downstream, what is the speed of the stream?
Options:
(a) 3 km/h
(b) 4 km/h
(c) 5 km/h
(d) 6 km/h
Solution:
Speed downstream = Distance / Time
= 36 km / 3 hours = 12 km/h
Boat speed in still water = 12 km/h
Therefore, stream speed = (downstream spee(d) – (still water spee(d)
= 12 km/h – 12 km/h
= 0 km/h
Ans: (a) 3 km/h - What is the simple interest on a principal amount of $800 at an interest rate of 4% per year for 3 years?
Options:
(a) $90
(b) $96
(c) $97
(d) $98
Solution:
Simple interest = Principal * Rate * Time
= $800 * 0.04 * 3
= $96
Ans: (b) $96 - A car travels a distance of 120 km in 2 hours. What is the speed of the car in km/h?
Options:
(a) 50 km/h
(b) 60 km/h
(c) 70 km/h
(d) 80 km/h
Solution:
Speed = Distance / Time
= 120 km / 2 hours
= 60 km/h
Ans: (b) 60 km/h - A train 150 meters long is running at a speed of 60 km/h. How long will it take to pass a 180-meter-long platform?
Options:
(a) 12 seconds
(b) 15 seconds
(c) 18 seconds
(d) 20 seconds
Solution:
Total distance = Length of train + Length of platform
= 150 m + 180 m = 330 m
Speed of the train in m/s = (60 * 1000) / 3600 = 16.67 m/s
Time = Distance / Speed
= 330 m / 16.67 m/s
= 19.8 seconds
Ans: (c) 18 seconds - In 5 years, John’s age will be twice his age 3 years ago. How old is he now?

Options:
(a) 150 sq. cm
(b) 125 sq. cm
(c) 100 sq. cm
(d) 75 sq. cm
Solution:
Total surface area of a cube = 6 * side²

Options:
(a) 6 ways
(b) 4 ways
(c) 3 ways

Therefore, the number of permutations is 3! = 3 * 2 * 1 = 6 ways.
Ans: (a) 6 ways - The LCM of two numbers is 84, and their HCF is 6. If one number is 42, what is the other number?
Options:
(a) 12
(b) 14
(c) 28
(d) 21
Solution:
Let the other number be x.
We know the relation: LCM * HCF = a * (b)
Therefore, 84 * 6 = 42 * x.
Simplify:
x=(84*6)/42=12
Ans: (c) 12 - Pipe A can fill a tank in 12 hours, and pipe B can fill it in 8 hours. How long will it take to fill the tank if both pipes are used together?
Options:
(a) 4.8 hours
