Entry fee in an exhibition was Re.1 .Later, this was reduced by 25% .Which increased the sale by 20% .Find the percentage increase in the number of visitors?


A) 40%

B) 50%

C) 60%

D) 70%

E) 80%

Answer:

Option C

Explanation:

Let initially 100 visitors visit the exhibition daily

Entry fee per person = Re.1

Reduction in entry fee = 25% of Re.1

Reduced entry fee = Rs. 114

 Rs. =34

Entry fee collected from 100 visitors  = Rs .100

Increase in sale of tickets = 20%

Total sale after that =100+20% of 100

=100+20=Rs.120

If entry fee collected = Rs 34 then no of visitors  = 1

If entry fee collected is Rs 120, then no of visitors = 1×4×1203=160

Increase % in number of visitors =160100=60%
