The Correct Option is A, D
Solution and Explanation
Premises:
1. Soli likes either logic or biology.
2. If Soli likes logic, then he is not happy.
3. Neither Soli nor Rupinder likes biology. → So Soli cannot like biology.
Step 1: Apply premise (3)
Since Soli cannot like biology, the only option left is that Soli likes logic.
Step 2: Apply premise (2)
If Soli likes logic, then he is not happy. Therefore, Soli is not a happy person.
Step 3: Check options
(A) Soli is not a happy person → True.
(B) Rupinder is not a happy person → No information given.
(C) Rupinder is a happy person → No information given.
(D) Soli likes logic → True.

Top Questions on Logical and Analytical Reasoning Skills
An investment company, Win Lose, recruit's employees to trade in the share market. For newcomers, they have a one-year probation period. During this period, the employees are given Rs. 1 lakh per month to invest the way they see fit. They are evaluated at the end of every month, using the following criteria:
1. If the total loss in any span of three consecutive months exceeds Rs. 20,000, their services are terminated at the end of that 3-month period,
2. If the total loss in any span of six consecutive months exceeds Rs. 10,000, their services are terminated at the end of that 6-month period.
Further, at the end of the 12-month probation period, if there are losses on their overall investment, their services are terminated.
Ratan, Shri, Tamal and Upanshu started working for Win Lose in January. Ratan was terminated after 4 months, Shri was terminated after 7 months, Tamal was terminated after 10 months, while Upanshu was not terminated even after 12 months. The table below, partially, lists their monthly profits (in Rs. ‘000’) over the 12-month period, where x, y and z are masked information.
Note:
• A negative profit value indicates a loss.
• The value in any cell is an integer.
Illustration: As Upanshu is continuing after March, that means his total profit during January-March (2z +2z +0) ≥
Rs.20,000. Similarly, as he is continuing after June, his total profit during January − June ≥
Rs.10,000, as well as his total profit during April-June ≥ Rs.10,000.
