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?
50p − 1800
Number of students = (p)
Money collected from each student = ( ext{Rs }50)
Total money collected = (50 imes p)
So, total = (50p)
They pay advance for transport = ( ext{Rs }1800)
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).
