Question

Ragini went to watch a 4D animated short movie in a mall. There were 7 different animated movies playing on the screen. She paid Rs. 150 for one show of a movie. In Rs. 800 how many different animated movies she can see (assume she spent money only on movie tickets)?

• A. 4
• B. 5
• C. 6
• D. 7

Answer 1

The correct option is B

5

Ragini watched one movie in Rs 150.

So the ratio of cost to a movie is 150: 1.

Tickets of a movie can be bought to watch the full movie i.e.if someone wants to watch a movie, they can buy tickets for Rs 150 only.

They cannot buy a ticket for the half movie with Rs 75.

Let "x” be the number of movies she can watch,

$So,\frac{\left(Priceofticket\right)}{\left(Numberoftickets\right)}=\frac{150}{1}=\frac{800}{x}$

Now by cross multiplying
$x=\frac{800}{150}=5.33$

As the number of movie tickets can only be a whole number, so it will be 5.

The number of movies she can watch is 5.
