Hi there! ;) The answer to your question is 0.85 or 85%. I got the answer because I divided 66/78(66 divided by 78) which equals 0.845 but I rounded it because 5,6,7,8,9 means round up.
Hope I helped! :D
On the 60th visit, you will get both free dessert and a free beverage.
A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.
The hint which is present in a given pattern hides in the pattern only.
For example 2,4,6,8 in this, the difference between any two-term is only 2 and this will be its specific pattern.
Another example is 2,4,16,256 in this pattern each term is the square of the previous term and this will become its specific pattern.
Given,
At every 12th visit, we get a beverage
At every 15th visit, we get dessert
So let's say at x visit we get both
So,
x should be a minimum result of multiple of both 12 and 15
So,
12 (5) = 60 and 15(4) = 60
So 60 is the minimum result.
Hence, On the 60th visit, you will get both free dessert and a free beverage.
