Top 60 Practice MCQs for OSSSC LSI, Forester, FG
- 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. - Refer to the numerical series given below and answer the following questions:
435 224 786 823 902
When all the digits in each of the given numbers are arranged in ascending order, which number becomes the highest?
(a) 435
(b) 224
(c) 786
(d) 823
Answer: (c)786
Solution: When the digits are arranged in ascending order within the number, the new numbers formed are:
435 – 345
224 – 224
786 – 678
823 – 238 - From the given options, find the pair which is similar to the given pair: 8:4
(a) 27:9
(b) 216:32
(c) 72:24
(d) 45:5
Answer: (a) 27:9
Solution:
The pattern followed is “Cube of a number: square of the same number”
So, (2×2×2) : (2×2)
= 8:4
Similarly, (3×3×3) : (3×3)
= 27:9 - At what time between 5.30 and 6 will the hands of a clock be at right angles?
A. 44 minutes past 5
B.44 ( 7/11) minutes past 5
C.43 ( 7/11) minutes past 5
D. 43 minutes past 5
Ans: C.43 ( 7/11) minutes past 5
Solution:
Given: H = 5 and A = 90, since 5 and 6 lies in the first half, a positive sign is considered.
T = 2/11 [H*30±A]
T = 2/11 [5*30+90]
T = 2/11 [240] = 480/11= 43( 7/11) - How many times in a day, the hands of a clock are straight?
A. 22
B. 24
C. 44
D. 48
Ans: C. 44
Solution:
The hands of clocks make a straight line of 180° about 22 times in 24 hours. Also, the hands coincide 22 times in 24 hours, the coincidence of the hands also forms a straight line. Hence, the total straight lines are 22+22 = 44. - If X is the brother of Y and Y is the daughter of Z, what is X to Z?
(A) Father
(B) Brother
(C) Son
(D) Uncle
Ans:- (C) Son
Sol:- Given that X is the brother of Y, it implies they share the same parents. Additionally, if Y is the daughter of Z, then Z is one of their parents. Consequently, we can deduce that X is the son of Z.
So, it is clear that X is a son of Z - Which year in the future will have the same calendar exactly as 2009?
(A) 2010
(B) 2013
(C) 2015
(D) 2017
ANS:- (C) 2015
Sol:- To find the year in the future that will have the same calendar as 2009, we need to consider the cycle of leap years and the number of odd days.
First, let’s note that 2009 is an ordinary year, so it has 1 odd day. - What is the missing number in the series: 5, 12, 21, 32, ?, 60?
A) 42
B) 45
C) 48
D) 50
ANS:- B) 45
Sol:- To identify the pattern in the series, let’s examine the differences between consecutive numbers:
The difference between 12 and 5 is 12 − 5 = 7.
The difference between 21 and 12 is 21 − 12 = 9.
The difference between 32 and 21 is 32 − 21 = 11.
It seems that the differences between consecutive numbers are increasing by 2.
Let’s continue this pattern:
The difference between the missing number and 32 should be 13.
Adding 13 to 32 gives us 32 + 13 = 45.
difference between 45 and 60 is 60 − 45 = 15
Therefore, the missing number in the series is 45 - Complete the analogy:
5 : 25:: 6:?
Options:
a) 31
b) 36
c) 30
d) 29
ANS:- b) 36
Sol:- The relationship between 5 and 25 is that 5 squared equals 25. Similarly, 6 squared equals 36. Therefore, the correct answer is 36. - Statements:
(A) All resorts have scenery.
(B)Goa is a resort.
Conclusions
I. Goa has scenery.
II. Places other than resorts don’t
have scenery.
Options:-
(a) if only the conclusion I follow.
(b) if only conclusion II follows.
(c) if either I or II follows.
(d) if neither I nor II follows
ANS:- (a) if only the conclusion I follow.
Sol:- Let’s analyze each conclusion based on the given statements:
Statement (A): All resorts have scenery.
Statement (B): Goa is a resort.
Conclusion I: Goa has scenery.
This conclusion logically follows from the given statements. Since it is stated that all resorts have scenery, and it is given that Goa is a resort, we can conclude that Goa has scenery. So, the conclusion I follow.
Conclusion II: Places other than resorts don’t have scenery.
This conclusion cannot be logically inferred from the given statements. While it is stated that all resorts have scenery, it does not imply anything about places other than resorts. Other places can have scenery as well. So, conclusion II does not follow.
Based on the above analysis:
A conclusion I follow.
Conclusion II does not follow.
So, the correct option is (a) if only the conclusion I follow. - Shanu is facing south, She turns 90 degrees left, then she turns 90 degrees right, then she turns 180 degrees left. Now in which direction is she facing?
A) North
B) East
C) South
D) West
ANS:- A) North
Sol:- Let’s analyze Shanu’s movements:
Shanu starts facing South.
She turns 90 degrees left, which means she is now facing East.
Then she turns 90 degrees right from East, which means she is now facing South again.
Next, she turns 180 degrees left from South, which means she makes a complete turn and ends up facing North.
So, after all the movements, Shanu is facing North.
Therefore, Shanu is facing A) North - Antonyms: Incoherent ?
