Question

For a store contest,4 out of every 65 people who visited the store will receive a free dvd. If 455 people visit the store, how many dvds were given?

Answer 1

28

Explanation:

Given that there is a store contest. Out of 65 people who visit the store only 4 will be receiving a free dividend.

Remaining 61 will not receive.

There were 455 people who visited the stores.

Of these 455/65 times 4 persons would be given dividends.

i.e. Since 4 out of 65 would be given

no of visitors who received dividend= 455(4)/65 = 7(4) = 28

Hence answer is 28 persons would receive dividend.

Answer 2

28 dvds were given if 455 people visit the store.

Explanation:

4 out of every 65 people who visited the store will receive a free dvd.

Suppose,
`x` dvds were given if 455 people visit the store.

Now, according to the ratio of "people who got dvd" to "total number of people" , the equation will be.........

`(4)/(65)=(x)/(455)\\ \\ 65x= 455*4=1820\\ \\ x=(1820)/(65)=28`

So, the number of dvds given is 28.
