Question. 89

A class with p students has planned a picnic. Rs 50 per student is collected, out of which Rs 1800 is paid in advance for transport. How much money is left with them to spend on other items?

Answer:

50p − 1800

Detailed Answer with Explanation:

  1. Number of students = (p)

  2. Money collected from each student = ( ext{Rs }50)

  3. Total money collected = (50 imes p)

    So, total = (50p)

  4. They pay advance for transport = ( ext{Rs }1800)

  5. Money left = (Total collected) − (Advance paid)

    = (50p - 1800)

Final Answer: (50p - 1800)

Quick check (optional):

If (p = 40), then total collected = (50 imes 40 = 2000).

Money left = (2000 - 1800 = 200) (Rs 200 left for other items).
