CL Mock question :-
A small town Madhubani, in an effort to raise money, hired " Spice gals" to play in its civic stadium.
The gals offered to perform a concert for Rs. 10,000 and 20% of the gate receipts generated during
the concert. It is assumed that 10,000 people would attend. What admission charge per person
would the town have to charge to earn a profit of Rs. 25,000?
Sol: Let the charge per person be Rs.x
Then, 10000 + (10000*x)20/100 + 25000 = 10000x
=> x = 4.375
My doubt is, shouldn't the equation be,
10000 + (10000*x)20/100 + 25000 = 8000x,
Since, the town receives 80% of the gate receipts?
how many integers N between 4 and 100 are there such that remainder is (N+1)/6
when (N-4)! is divided by N?
