The Correct Option is C
Solution and Explanation
Step 1: Total shoppers = 240. Male:Female = 1:2 → Male = 80, Female = 160. Unhappy:Happy:Neutral = 3:4:5 → Unhappy = $3k$, Happy = $4k$, Neutral = $5k$, total = $12k = 240$ → $k=20$. So Unhappy = 60, Happy = 80, Neutral = 100.
Step 2: First-time shoppers = 65, Returning = 175.
Step 3: From condition ii: Happy first-time male : Happy returning male : Unhappy female : Neutral male : Neutral female : Happy female = 1:1:4:4:6:6. Let these be $a, a, 4a, 4a, 6a, 6a$ respectively.
Step 4: Total Happy = Happy first-time male + Happy returning male + Happy female = $a + a + 6a = 8a = 80$ → $a = 10$. So Happy first-time male = 10, Happy returning male = 10, Happy female = 60.
Step 5: Total male = 80 = Happy first-time male + Happy returning male + Neutral male + Unhappy male. Unhappy male not directly given. But we have Neutral male = $4a = 40$. So 80 = 10 + 10 + 40 + Unhappy male → Unhappy male = 20.
Step 6: Total female = 160 = Happy female + Neutral female + Unhappy female = 60 + $6a$ + $4a$ = 60 + 60 + 40 = 160, consistent.
Step 7: Happy male shoppers = Happy first-time male + Happy returning male = 10 + 10 = 20.
Step 8: Final Answer: 20.

- Read the information given below carefully and answer the question that follows: In an 8-week course, Professor Bala G. administered a test at the end of each week. Each of the 8 tests taken by Bala G. were scored out of 4 marks, and a student could only receive a non-negative integer score. Two students, namely, Puneet and Urvisha, took the 8 tests. In the first test, Puneet and Urvisha scored the same marks. From the second to 8 tests, Puneet scored the exact same non-zero marks. Urvisha scored the same marks as Puneet from the 5th test onwards. Puneet's total marks in the first three tests was the same as Urvisha's total marks in the first 2 tests. Also, Urvisha's marks in the first test, total marks of the first 2 tests, and total marks of the 8 tests were found to be in a geometric progression. Which of the following may be true?
