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?
Total number of students = p
Money collect from each student = Rs. 50
Total money collected = Rs. 50×p = 50p
Advance money paid for transport = Rs. 1800
Money left will be advance amount subtracted from total money collected.
Money left with them = Rs. (50p - 1800)
