Last Minute Revision Quiz for OSSSC RI, ARI, AMIN: 26 September 2024
- What is the volume of a cylinder with a radius of 3 cm and height of 10 cm?
Options:
(a) 282.74 cm³
(b) 282.45 cm³
(c) 282.50 cm³
(d) 283.33 cm³
Sol:
Volume of a cylinder = πr²h
= π * 3² * 10
= π * 9 * 10
= 282.74 cm³ (approx)
Ans: (a) 282.74 cm³ - What is the probability of rolling a sum of 7 with two six-sided dice?
Options:
(a) 1/6
(b) 1/9
(c) 1/12
(d) 1/36
Sol:
Possible ways to roll a 7: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1).
There are 6 outcomes out of 36 total outcomes.
Probability = 6 / 36 = 1 / 6
Ans: (a) 1/6 - A can complete a work in 10 days, and B can complete the same work in 15 days. How many days will it take if they work together?
Options:
(a) 6 days
(b) 5 days
(c) 7 days
(d) 8 days
Sol:
Work done by A in one day = 1/10
Work done by B in one day = 1/15
Together, their work per day = 1/10 + 1/15
= 3/30 + 2/30 = 5/30 = 1/6
So, together they will take 6 days to complete the work.
Ans: (a) 6 days - If 3 parts of a mixture contains 2 parts of salt, how much salt would be there in a mixture of 15 parts?
Options:
(a) 5 parts
(b) 6 parts
(c) 7 parts
(d) 10 parts
Sol:
Ratio of salt to mixture = 2/3
Therefore, salt in 15 parts = (2/3) * 15 = 10 parts
Ans: (d) 10 parts - 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
Sol:
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
Sol:
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
Sol:
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
Sol:
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

(a) Saturday
(b) Friday
(c) Monday
(d) Sunday
Answer:(a) Saturday
Explanation:
From 1 January 2016 to 31 December 2016 is exactly one year. Since one year consists of 366 days (2016 was a leap year), the number of days is equal to 52 weeks plus 2 extra days. Therefore, the day of the week shifts by 2 days from Friday (1 January 2016) to Saturday (31 December 2016). Hence, the answer is Saturday. - What was the day of the week on 31 January 2007?
(a) Monday
(b) Tuesday
(c) Thursday
(d) Wednesday
Answer:(d) Wednesday
Explanation:
To find the day of the week on 31 January 2007, we can use a known reference date, such as 1 January 2007, which was a Monday. Since January 31st is 30 days after January 1st, it is exactly 4 weeks and 2 extra days later. Therefore, the day of the week shifts from Monday to Wednesday. Hence, the answer is Wednesday. - If 18 October 2006 was a Wednesday, what was the day of the week on 17 October 2000?
(a) Tuesday
(b) Wednesday
(c) Monday
(d) Sunday
Answer:(a) Tuesday
Explanation:
To calculate the day of the week on 17 October 2000, given that 18 October 2006 was a Wednesday, we need to calculate the difference in days. The difference between the two dates is 6 years, which includes 2 leap years (2000 and 2004). This results in a total of 2191 days (6*365 + 2). This is equivalent to 313 weeks and 0 days. Since the number of days is a multiple of 7, the day of the week will shift back to Tuesday.
