Question : Directions: Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow (s) from the statements. Statements: I. Some M are Q. II. All V are Q. Conclusions: I. Some Q are M. II. No M is V.
Option 1: Both conclusions I and II follow
Option 2: Only conclusion I follows
Option 3: Neither conclusion I nor II follows
Option 4: Only conclusion II follows
Correct Answer: Only conclusion I follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyze the conclusions – Conclusion (I): Some Q are M – From the Venn diagram, it is evident that the circles representing Q and M overlap and have
Question : Directions: In a certain code language, ACCENT is coded as CCATNE. What is the code for VENDOR in that code language?
Option 1: VENROD
Option 2: NVEDOR
Option 3: NEVROD
Option 4: NEVORD
Correct Answer: NEVROD
Solution : Given: ACCENT is coded as CCATNE.
Divide the letters of the ACCENT into two parts and then write them in the reverse order. ACCENT→ACC / ENT Reverse the order of the letters→CCATNE So, ACCENT is coded as CCATNE. Similarly, VENDOR→VEN / DOR Reverse the order
Question : Directions: Two statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow (s) from the statements. Statements: Some cars are fast. Some fast is slow. Conclusions: I. Some cars are not slow. II. Some slow is fast.
Option 2: Only conclusion II follows
Option 4: Only conclusion I follows
Correct Answer: Only conclusion II follows
Let's analyse the conclusions – Conclusion (I): Some cars are not slow – From the Venn diagram, it is evident that there is no direct relation between cars and
Question : Directions: In a certain code language, GRAY is coded as 718125, FOMK is coded as 6151311. How will CBHL be coded in that code language?
Option 1: 23812
Option 2: 32812
Option 3: 38212
Option 4: 32821
Correct Answer: 32812
Solution : Given: GRAY is coded as 718125, and FOMK is coded as 6151311.
The code is obtained by writing the positional values of the alphabet in the given words. GRAY→G(7), R(18), A (1), Y(25) = 718125 FOMK→F(6), O(15), M(13), K(11) = 6151311 CBHL→C(3), B(2), H(8), L(12)
Question : Directions: A is B's brother, C is A's mother, D is C's father, and B is D's granddaughter. How is B related to F who is A's son?
Option 1: Aunt
Option 2: Cousin
Option 3: Niece
Option 4: Daughter
Correct Answer: Aunt
Solution : As per the given information the family tree will be as follows –
Here, the quadrilateral represents the male and the circular figure represents the female in the figure.
So, from the above family tree, B is the Aunt of F. Hence the first option
Question : If the momentum of a body is doubled, the kinetic energy is:
Option 1: becomes 1/4 times
Option 2: unchanged
Option 3: doubled
Option 4: becomes 4 times
Correct Answer: becomes 4 times
Solution : The correct option is becomes 4 times.
Velocity and momentum are directly related. An object's velocity is twice as high if its momentum doubles, but its mass does not (the object's velocity stays below the speed of light). When the velocity doubles,
Question : A number is increased by 5% and then the increased number is decreased by 5%. What is the net increase or decrease per cent?
Option 1: 0.25% decrease
Option 2: 0.75% increase
Option 3: 1% increase
Option 4: 0.50% decrease
Correct Answer: 0.25% decrease
Solution : Let $x$ be the number. Increase = 5% Increased number = $x$ + 5% of $x$ = 105% of $x$ = $1.05x$ Decrease = 5% Final number = $1.05x$ – 5% of $1.05x$ = $0.95×1.05x$ = $0.9975x$ Net decrease = $\frac{x – 0.9975x}{x}$ ×
Question : _____________ won the women’s singles title at the Swiss Open Super 300 badminton tournament in 2022.
Option 1: P. V. Sindhu
Option 2: Kirsty Gilmour
Option 3: Ashmita Chaliha
Option 4: Busanan Ongbamrungphan
Correct Answer: P. V. Sindhu
Solution : The correct answer is P. V. Sindhu.
P. V. Sindhu won the women's singles title in the Swiss Open Super 300 badminton event of 2022. Veteran Indian shuttler P. V. Sindhu defeated Thailand's Busanan Ongbamrungphan in straight games to win the women's
Question : The average daily expenditure of Mohan over 4 days is INR 120. If his expenditure on the first 3 days are INR 60, INR 150 and INR 140, respectively, then what is his expenditure on the $4^{\text {th }}$ day?
Option 1: INR 145
Option 2: INR 110
Option 3: INR 130
Option 4: INR 120
Correct Answer: INR 130
Solution : Average daily expenditure of Mohan over 4 days = INR 120 Sum of expenditure over 4 days = 120 × 4 = 480 Expenditure on the first 3 days = INR 60, INR 150 and INR 140 Let $x$ be the expenditure on the
Question : If the average of 20, 40, 50, Y and Z is 45, then what is the average of Y and Z?
Option 1: 58.5
Option 2: 57.5
Option 3: 56.5
Option 4: 55
Correct Answer: 57.5
Solution : The average of 20, 40, 50, Y, and Z is 45. The sum of these numbers = 45 × 5 = 225 So, the sum of Y and Z is, Y + Z = 225 – 20 – 40 – 50 = 115 Average =
