When ticket prices to a water park are increased in the ratio 11:12 then the number of daily visitors to the park fall in the ratio 8:7. If the daily revenues before the increase in ticket price was Rs 176,000, then find the daily revenues after the increase in ticket price.
Let say, new price is 12k and old price was 11k .
And, Previous visitors was 8m and new visitors are 7m.
According to question ,
 $$8m\times11k=176000\ .$$
or, $$mk=\frac{176000}{88}=2000\ .$$
So, New revenue =Â $$7m\times12k=7\times12\times2000\ =168000\ .$$
D is correct choice.
