Solution
Let the cost of the entry ticket initially and at present be 10x and 13x respectively.
Let the number of visitors initially and at present be 6y and 5y respectively.
Initially, total collection = 10x × 6y = 60 xy
At present, total collection = 13x × 5y = 65 xy
Ratio of total collection = 60 xy : 65 xy = 12 : 13
Thus, the total collection has increased in the ratio 12 : 13.
