• Question 1 of 5 1. Question With reference to the above passage, the following assumptions have been made: Corporate loan defaults have a more severe impact on banking health than small-scale defaults. Improving governance and accountability can reduce the incidence of willful corporate defaults. Which of the above assumptions is/are valid? (a) I only (b) II only (c) Both I and II (d) Neither I nor II Correct Answer: C Explanation: Assumption I is valid: The passage highlights that large corporate loan defaults have led to significant erosion of banking capital and affect taxpayers and credit access. This supports the assumption. Assumption II is valid: The passage clearly states that governance reform and accountability are required to prevent strategic default, directly validating the second assumption. Hence, both assumptions logically follow from the passage. Incorrect Answer: C Explanation: Assumption I is valid: The passage highlights that large corporate loan defaults have led to significant erosion of banking capital and affect taxpayers and credit access. This supports the assumption. Assumption II is valid: The passage clearly states that governance reform and accountability are required to prevent strategic default, directly validating the second assumption.

• Question 2 of 5 2. Question The incomes of E and F are in the ratio 2:3. E’s income increases by 30%, and total income increases by 24% to ₹74,400. What is the percentage increase in F’s income? (a) 15% (b) 16% (c) 18% (d) 20% Correct Answer: D Solution: Let original incomes be 2x and 3x ⇒ Total = 5x New total = 5x × 1.24 = 6.2x Given new total = ₹74,400 ⇒ 6.2x=74,400⇒x=12,000 E’s new income = 2x × 1.30 = ₹31,200 F’s new income = 74,400 − 31,200 = ₹43,200 F’s original income = 3x = ₹36,000 % increase = 7,200/36,000×100=20 Answer: (d) 20% Incorrect Answer: D Solution: Let original incomes be 2x and 3x ⇒ Total = 5x New total = 5x × 1.24 = 6.2x Given new total = ₹74,400 ⇒ 6.2x=74,400⇒x=12,000 E’s new income = 2x × 1.30 = ₹31,200 F’s new income = 74,400 − 31,200 = ₹43,200 F’s original income = 3x = ₹36,000 % increase = 7,200/36,000×100=20 Answer: (d) 20%
#### 2. Question
The incomes of E and F are in the ratio 2:3. E’s income increases by 30%, and total income increases by 24% to ₹74,400. What is the percentage increase in F’s income?
Solution:
• Let original incomes be 2x and 3x ⇒ Total = 5x
• New total = 5x × 1.24 = 6.2x
• Given new total = ₹74,400 ⇒
6.2x=74,400⇒x=12,000
E’s new income = 2x × 1.30 = ₹31,200
• F’s new income = 74,400 − 31,200 = ₹43,200
• F’s original income = 3x = ₹36,000
• % increase = 7,200/36,000×100=20
Answer: (d) 20%
Solution:
• Let original incomes be 2x and 3x ⇒ Total = 5x
• New total = 5x × 1.24 = 6.2x
• Given new total = ₹74,400 ⇒
6.2x=74,400⇒x=12,000
E’s new income = 2x × 1.30 = ₹31,200
• F’s new income = 74,400 − 31,200 = ₹43,200
• F’s original income = 3x = ₹36,000
• % increase = 7,200/36,000×100=20
Answer: (d) 20%

Answer: (a) Statement-1 and Statement-2 are sufficient
#### 3. Question
Consider the following question and the statement that follows:
Question: In a garden, there are rabbits and peacocks. How many rabbits are there?
Statement 1: The total number of animals is 50. Statement 2: The total number of legs is 140. Statement 3: The number of peacocks is odd.
Which of the following is correct with respect to the above?
• (a) Statement-1 and Statement-2 are sufficient
• (b) Statement-2 and Statement-3 are sufficient
• (c) Statement-1 and Statement-3 are sufficient
• (d) All three statements are not sufficient
Answer – A Solution
Let rabbits = R (4 legs), peacocks = P (2 legs)
From Statement 1:
R+P=50(Eq.1)
From Statement 2:
4R+2P=140(Eq.2)
Divide Eq.2 by 2:
2R+P=70(Eq.3)
Subtract (1) from (3):
(2R+P)−(R+P)=70−50⇒R=20⇒P=30
Exact numbers found; Statement 3 not required.
Answer: (a) Statement-1 and Statement-2 are sufficient
Answer – A Solution
Let rabbits = R (4 legs), peacocks = P (2 legs)
From Statement 1:
R+P=50(Eq.1)
From Statement 2:
4R+2P=140(Eq.2)
Divide Eq.2 by 2:
2R+P=70(Eq.3)
Subtract (1) from (3):
(2R+P)−(R+P)=70−50⇒R=20⇒P=30
Exact numbers found; Statement 3 not required.
Answer: (a) Statement-1 and Statement-2 are sufficient
• Question 4 of 5 4. Question A boat takes 28 hours for travelling downstream from point A to point B and coming back to point C midway between A and B. If the velocity of the stream is 6km/hr and the speed of the boat in still water is 9 km/hr, what is the distance between A and B? a) 115 km b) 120 km c) 140 km d) 165 km Correct Answer : B Explanation: Downstream speed = 9+6 = 15 Upstream speed = 9-6 = 3 Now total time is 28 hours If distance between A and B is d, then distance BC = d/2 Now distance/speed = time, so d/15 + (d/2)/3= 28 Solve, d = 120 km Incorrect Answer : B Explanation: Downstream speed = 9+6 = 15 Upstream speed = 9-6 = 3 Now total time is 28 hours If distance between A and B is d, then distance BC = d/2 Now distance/speed = time, so d/15 + (d/2)/3= 28 Solve, d = 120 km
#### 4. Question
A boat takes 28 hours for travelling downstream from point A to point B and coming back to point C midway between A and B. If the velocity of the stream is 6km/hr and the speed of the boat in still water is 9 km/hr, what is the distance between A and B?
Answer : B
Explanation:
Downstream speed = 9+6 = 15 Upstream speed = 9-6 = 3
Now total time is 28 hours
If distance between A and B is d, then distance BC = d/2
Now distance/speed = time, so
d/15 + (d/2)/3= 28
Solve, d = 120 km
Answer : B
Explanation:
Downstream speed = 9+6 = 15 Upstream speed = 9-6 = 3
Now total time is 28 hours
If distance between A and B is d, then distance BC = d/2
Now distance/speed = time, so
d/15 + (d/2)/3= 28
Solve, d = 120 km
• Question 5 of 5 5. Question One evening before sunset two friends Sumit and Mohit were talking to each other face to face. If Mohit’s shadow was exactly to his right side, which direction was Sumit facing? a) North b) South c) West d) Data inadequate Correct Answer : B Explanation: In the evening, the sun is in the west and so the shadows fall towards the east. So, Mohit’s shadow fell towards the east. Now, since Mohit’s shadow fell towards right, therefore, Mohit is facing north. So Sumit, standing face to face with Mohit, was facing south. Incorrect Answer : B Explanation: In the evening, the sun is in the west and so the shadows fall towards the east. So, Mohit’s shadow fell towards the east. Now, since Mohit’s shadow fell towards right, therefore, Mohit is facing north. So Sumit, standing face to face with Mohit, was facing south.
