Answer»

Let the NUMBER of visitors initially be x. Thus, the total SALE = Rs. 100x

Now the ENTRY fee is reduced to 60%. Thus, new entry fee = Rs. 60

The sales are increased by 20%. Thus, new sales = 100x + 20% of 100x = 120x

New number of visitors = 120x/60 = 2x

% INCREASE in the number of visitors = [(2x - x)/x] × 100 = 100%

Hence, there is 100% increase in the visitors.
