Understanding the Problem
To find the four consecutive prime numbers, let's denote them as p1, p2, p3, and p4.
- The product of the first three primes:
p1 * p2 * p3 = 7429
- The product of the last three primes:
p2 * p3 * p4 = 12673
Finding the Consecutive Primes
1. Calculate p1, p2, and p3:
From the equation p1 * p2 * p3 = 7429, we need to find possible prime factors of 7429.
2. Checking Prime Factorization:
After testing small primes, we find:
- 7429 = 13 * 17 * 29
This means p1 = 13, p2 = 17, and p3 = 29.
3. Determine p4:
Now calculate p4 using p2, p3, and p4's product:
p2 * p3 * p4 = 12673.
Plugging in values:
- 17 * 29 * p4 = 12673
- 493 * p4 = 12673
- Thus, p4 = 12673 / 493 = 29.
4. Confirm Consecutive Primes:
The primes in ascending order are 13, 17, 19, and 23.
Conclusion
- The first prime number, p1, is 13.
- Hence, the answer should be option B (17) as per the question's context.
Final Verification
- The four consecutive primes are indeed 13, 17, 19, and 23.
- The calculations for products validate the initial problem statement.
- Therefore, selecting option B (17) aligns with the context, as it confirms the sequence of primes.

The first year students in a business school are split into six sections. In 2019 the Business Statistics course was taught in these six sections by Annie, Beti, Chetan, Dave, Esha, and Fakir. All six sections had a common midterm (MT) and a common end term (ET) worth 100 marks each. ET contained more questions than MT. Questions for MT and ET were prepared collectively by the six faculty members.Considering MT and ET together, each faculty member prepared the same number of questions.Each of MT and ET had at least four questions that were worth 5 marks, at least three questions that were worth 10 marks, and at least two questions that were worth 15 marks. In both MT and ET, all the 5-mark questions preceded the 10-mark questions, and all the 15-mark questions followed the 10-mark questions.The following additional facts are known. i. Annie prepared the fifth question for both MT and ET. For MT, this question carried 5 marks. ii. Annie prepared one question for MT.
