Answer 2

Total collection increased in ratio 13 : 12

Solution:

Cost ratio 10 : 13

visitors ratio 6 : 5

Let us consider the original Tickets cost Rs 10 and and number of visitors is 600

Original revenue: 10 x 100 = Rs 6000

After increase in cost of ticket

Tickets cost Rs 13 and number of visitors is 500

New Revenue: 13 x 500 = Rs 6500

Thus,

$Increase\ in\ collection = \frac{6500}{6000} = \frac{13}{12}$

Thus, total collection increased in ratio 13 : 12
