Mathematics

Sav [38]3 years ago

Answer:

The lower the age of Benny and Jenny, the% between the age of both, the more it decreases

Step-by-step explanation:

To calculate the exact percentage, the age of one of the two is necessary. I demonstrate it with several examples.

Let B be Benny's age

Let J be Jenny's age

We are told that Benny's age is 200% Jenny's age, we know that 200% is 2, therefore:

B / J = 2

Now if B = 2 and J = 1

2/1 = 2

After 4 years:

B + 4 / J + 4 = (2 + 4) / (1 + 4) = 1.2, i.e. 120%

Another example, if B = 4 and J = 2

4/2 = 2

After 4 years:

B + 4 / J + 4 = (4 + 4) / (2 + 4) = 1.33, that is 133%

Another example, if B = 6 and J = 3

6/3 = 2

After 4 years:

B + 4 / J + 4 = (6 + 4) / (3 + 4) = 1.43, that is 143%

The conclusion is that the lower the age of Benny and Jenny, the% between the age of both, the more it decreases.
