Ultimate Last-Minute Quiz for OSSSC RI, ARI, AMIN
- The total age of three Girls in a family is 28 years. What will be the total of their ages after three years?
(a) 37 years
(b) 35 years
(c) 30 years
(d) 40 years
Ans: (a) 37 years
Solution:
Given,
Total age of three girls = 28 years
After three years, the age of each girl will increase by 3.
So, the total age after three years = 28 + 3 × 3
= 28 + 9
= 37
Therefore, the total age of three girls after three years will be 37 years. - Find the product of all the numbers present on the calculator pad.
(a) 0
(b) 1
(c) 2
(d) 4
Ans; (a) 0
Solution:
Numbers on the calculator pad = 0,1, 2, 3, 4, 5, 6, 7, 8, 9
Product of all these numbers = 0 × 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 = 0 {since the product of any number with 0 is also 0) - Tarun ran 12 laps every day for two weeks. How many laps did she run in all?
(a) 177
(b) 168
(c) 189
(d) 186
Ans: (b) 168
Solution:
Number of laps ran by Tarun in a day = 12
Number of day = 2 weeks = 2 × 7 days = 14 days
Total laps run by Tarun in 2 weeks = 12 × 14 = 168 - Simplify: 135 – 19 × 2 + 15
(a) 110
(b) 111
(c) 112
(d) 113
Ans: (c) 112
Solution:
135 – 19 × 2 + 15
= 135 – 38 + 15
= 150 – 38
= 112
Therefore, 135 – 19 × 2 + 15 = 112. - Find the next term of the arithmetic sequence 177, 173, 169, 165,…
(a) 115
(b) 151
(c) 116
(d) 161
Ans: (d) 161
Solution:
The given arithmetic sequence is:
177, 173, 169, 165,…
Here, 173 – 177 = -4
169 – 173 = -4
165 – 169 = -4
So, the next term = 165 – 4 = 161 - Sunil’s annual income is Rs. 289000. His annual savings amount to Rs. 36000. What is his total yearly expenditure?
(a) Rs. 252000
(b) Rs. 253000
(c) Rs. 259000
(d) Rs. 254000
Ans: (b) Rs. 253000
Solution:
Given,
The annual income of Sunil = Rs. 289000
Annual savings = Rs. 36000
Total yearly expenditure of Sunil = Rs. 289000 – Rs. 36000 = Rs. 253000 - Find the value of 45 ÷ 9 × 4 + 15 – 8
(a) 27
(b) 24
(c) 26
(d) 20
Ans: (a) 27
Solution:
45 ÷ 9 × 4 + 15 – 8
= 5 × 4 + 15 –8
= 20 + 15 – 8
= 35 – 8
= 27
Hence, 45 ÷ 9 × 4 + 15 – 8 is 27. - Simplify the numerical expression: [36 ÷ (-9)] ÷ [(-24) ÷ 6]
(a) 0
(b) 1
(c) 2
(d) 3
Ans: (b) 1
Solution:
[36 ÷ (-9)] ÷ [(-24) ÷ 6]
This can be written as:
= (36/-9) ÷ (-24/6)
= (-4) ÷ (-4)
= -4/-4
= 4/4
= 1
Thus, [36 ÷ (-9)] ÷ [(-24) ÷ 6] = 1. - Find the missing number in the following:
7 – 24 ÷ 8 × p + 6 = 1
(a) 5
(b) 6
(c) 4
(d) 3
Ans: (c) 4
Solution:
7 – 24 ÷ 8 × p + 6 = 1
7 – (24/8) × p + 6 = 1
7 – 3 × p + 6 = 1
13 – 3 × m = 1
⇒ 3 × p = 13 – 1
⇒ 3 × p = 12
⇒ p = 12/3
⇒ p = 4
Therefore, the missing number is 4. - Sonali bought 96 toys priced equally for Rs. 12960. The amount of Rs. 1015 is still left with him. Find the cost of each toy and the amount he had.
(a) Rs. 13970
(b) Rs. 13980
(c) Rs. 13960
(d) Rs. 13975
Ans: (d) Rs. 13975
Solution:
Given,
Number of toys Sonali bought = 96 toys
Cost of 96 toys = 12960
Cost of one toy = 12960/96 = 135
Amount left with him = 1015
Amount he gave = 12960
Amount he had initially = 12960 + 1015 = 13975
Thus, the cost of each toy was Rs. 135, and he had the amount of Rs. 13975. - Cup is to coffee as bowl is to:

(a) 90 degrees
(b) 187.5 degrees.
(c) 120 degrees
(d) 135 degrees
Ans: (b) 187.5 degrees
Explanation:
To find the angle between the hour hand and the minute hand at 3:45 PM:The hour hand will be slightly past 3 but not yet at 4, so it will be closer to 3.
The minute hand will be at 9 (since 45 minutes is three-quarters of an hour).
The angle formed between the hour hand and the 12 o’clock position is (3 * 30) + (45/2) = 97.5 degrees.
The angle formed between the minute hand and the 12 o’clock position is 45 * 6 = 270 degrees.
The difference between these two angles gives the angle between the hour hand and the minute hand: 270 – 97.5 = 172.5 degrees.
However, since we want the smaller angle between them, we subtract this from 360 degrees: 360 – 172.5 = 187.5 degrees. - If a clock gains 5 minutes every hour, how many minutes will it gain in a day?
(a) 120 minutes
(b) 240 minutes
(c) 300 minutes
(d) 360 minutes
Ans: (c) 300 minutes
Explanation:The clock gains 5 minutes every hour, which means it gains 60 minutes every 12 hours.
Therefore, in a 24-hour period, it will gain 60 * 2 = 120 minutes.
So, in a day, it will gain 120 + 120 = 240 minutes.
However, it starts at midnight and finishes at midnight, so it gains an extra 60 minutes, making it a total of 240 + 60 = 300 minutes in a day.
These questions test the understanding of angles and time relationships on a clock. - In a line of 10 boys, if A is seventh from the left and B is ninth from the right, how many boys are there between A and B?

(b) 2
(c) 3

Ans: (a) 1
Solution: A is in the 7th position from the left, and B is in the 9th position from the right, so there is 1 boy between them. - ଯୌଗିକ ବାକ୍ୟକୁ ସରଳ ବାକ୍ୟ ରେ ପରିଣତ କର ?ସୁଦାମା ଦରିଦ୍ର, କିନ୍ତୁ ବନ୍ଧୁବତ୍ସଳ ଥିଲେ ।
