Question

James is a shop owner he gives his customer full bottle of soft drink in return for five empty bottles William has 77 empty bottles and can used them to get full soft drink bottles how many filled bottle will he be able to collect ?

Answer 1

5 empty bottles => 1 full bottle

Therefore, 77 empty bottles è 15 full bottles (5 x 15 = 75) and 2 empty bottles => Eqn 1  

From Eqn 1: If Williams empties the 15 full bottles, they become empty.

So, now he has 15 + 2 = 17 empty bottles.

With 17 empty bottles, he gets 3 full bottles (3 x 5 =15) and 2 empty bottles => Eqn 2.

From Eqn 2: If William empties the 3 full bottles, they become empty.

So, now he has 3 + 2 = 5 empty bottles.

As 5 empty bottles = 1 full bottle, he gets that too.

So, totally Williams gets 15 + 3 + 1 = 19 full bottles.

Answer 2

Thank you for asking the question.

let me help you finding the answer.

I think this a one simple question
shop owner gives 1 filled bottle for  every 5  empty bottle
so 5 empty bottle = 1 filled bottle 
as the william has 77 bottles so we can easily calculated the answer
77 empty bottles will result in = 15 filled bottles while lefting behindd 2 extra empty bottles.

I hope this will help you.
