Question 1 of 5
1. Question
Two statements S1 and S2 are given below followed by a question:
S1: The sales booked by a salesman in March 2005 minus his 5% commission was Rs. 3,04,000.
S2: The sales booked by the salesman in March 2005 was 125% of Rs. 2,56,000.Question:
What was the sales booked by the salesman in March 2005?Which one of the following is correct in respect of the above statements and the question?
Correct
Answer: (c)
Explanation:
From S1:
After deducting 5% commission, 95% of sales = Rs. 3,04,000
So total sales = Rs. 3,20,000
So S1 alone is sufficient.
From S2:
125% of Rs. 2,56,000 = Rs. 3,20,000
So S2 alone is also sufficient.
Therefore, both S1 and S2 independently are sufficient.

Question 2 of 5
2. Question
Three traffic lights change colours from green to red and again red to green at different intervals. Signal P changes every 15 seconds, Signal Q changes every 25 seconds, and Signal R changes every 40 seconds. If they all turn green together at 7:30 a.m., when will they next turn green together?
Correct
Answer: (b)
Explanation:
We find the LCM of 15, 25 and 40.
15 = 3 × 5
25 = 5 × 5
40 = 2 × 2 × 2 × 5LCM = 2 × 2 × 2 × 3 × 5 × 5 = 600 seconds
600 seconds = 10 minutes
So they will next turn green together at 7:40 a.m.
So the correct answer is (b) 7:40 a.m.
Incorrect
Answer: (b)
Explanation:
We find the LCM of 15, 25 and 40.
15 = 3 × 5
25 = 5 × 5
40 = 2 × 2 × 2 × 5LCM = 2 × 2 × 2 × 3 × 5 × 5 = 600 seconds
600 seconds = 10 minutes
So they will next turn green together at 7:40 a.m.
So the correct answer is (b) 7:40 a.m.

Question 3 of 5
3. Question
Consider the following statements:
I. If a number is divisible by 18, then it must be divisible by 9 and 2.
II. If a number is divisible by 9 and 2, then it must be divisible by 18.Which of the statements given above is/are correct?
Correct
Answer: (c)
Explanation:
Statement I:
18 = 9 × 2
So any number divisible by 18 must be divisible by both 9 and 2.
This is true.Statement II:
If a number is divisible by both 9 and 2, then it is divisible by their LCM, which is 18.
So this is also true.Incorrect
Answer: (c)
Explanation:
Statement I:
18 = 9 × 2
So any number divisible by 18 must be divisible by both 9 and 2.
This is true.Statement II:
If a number is divisible by both 9 and 2, then it is divisible by their LCM, which is 18.
So this is also true. -
Question 4 of 5
4. Question
In organisational settings, recruitment and advancement are often expected to follow criteria related to competence, performance and experience. However, in certain contexts, personal connections and familiarity may influence these processes. Such patterns can shape how opportunities are distributed, sometimes affecting perceptions of fairness within the organisation.
Over time, these dynamics may interact with workplace culture, employee motivation and patterns of trust. Where decisions are perceived to be influenced by proximity rather than performance, responses among employees may vary, influencing engagement, retention and expectations regarding career progression.
Which one of the following statements best reflects the central idea conveyed by the passage?
Correct
Answer: (a)
Explanation
Option (b) is incorrect:
The passage indicates influence, not predominance of personal connections.Option (c) is incorrect:
It mentions multiple interacting factors, not a primary determinant.Option (d) is incorrect:
Engagement is discussed as one outcome, not the core focus.Option (a) is correct:
It captures the interaction between merit and relational factors shaping outcomes.Incorrect
