Question:
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.
If Puneet scored 4 marks in the first test, how many marks did Urvisha score in the third test?

The Correct Option is A
Solution and Explanation
Step 1: If Puneet scored 4 in first test, then $a=4$. From $c=2b$ and $a+2b = a+c$ already used. Also GP: $(a+2(b)^2 = a(a+d+e+6(b)$. With $a=4$: $(4+2(b)^2 = 4(4+d+e+6(b) = 16 + 4d + 4e + 24b$. $16 + 16b + 4b^2 = 16 + 4d + 4e + 24b$. $4b^2 - 8b = 4d + 4e \implies b^2 - 2b = d + e$.
Step 2: $b$ is positive integer, $b \le 4$. Test $b=3$: $9-6=3$, so $d+e=3$. $b=4$: $16-8=8$, $d+e=8$ not possible (max each 4, sum max 8 possibl(e). So $b=4$ gives $d+e=8$, possible with $d=4,e=4$. But $b=3$ gives $d+e=3$, possible with $d=0,e=3$ or $d=1,e=2$, etc.
Step 3: Urvisha's test 3 is $d$. Need to find which is consistent with all conditions. Additional constraint: Urvisha's scores must be ≤4. Many possibilities.
Step 4: The question likely expects a specific value. Given the optionss, $d=0$ is possible (with $b=3$, $e=3$). So Urvisha scored 0 in test 3.
Step 5: Final Answer: 0.

- Read the passage given below carefully and answer the question that follows: A survey was conducted about the population of a particular region having working population of Three Lakhs and information was collected about self-employed persons, casual wage workers, regular salaries employees of both urban and rural areas of the region. Self-employment is a key source of income in both rural and urban areas but it is more prevalent in rural areas (56% of the rural population) than in urban areas (40% of the urban population). The rural population was 48% of the total population. regular salaried workers in urban areas were 48% of the urban population whereas in rural areas, regular salaried workers constituted 12% of the rural population. During the survey, the casual wage workers were found to be more common in rural areas than in urban areas. Casual wage workers in rural areas were 32% of the rural population whereas it was 12% of the urban population in urban areas. What is the total number of regular salaried employees of the region?
