Question

A roller coaster ride costs ₹100 for half an hour. Shimpy wishes to ride for 2 hours. How much she has to pay?

• A. ₹100
• B. ₹200
• C. ₹300
• D. ₹400

Answer 1

The correct option is D ₹400

Since, cost for half an hour ride = ₹100
$\Rightarrow$ cost for 0.5 hours ride = ₹100

$\therefore \text{Cost for 1 hour ride}=\frac{100}{0.5}\times 1=₹200$

$\Rightarrow$ Cost for 2 hours ride = $200\times 2=₹400$

So, Shimpy has to pay ₹400.
