<h3><u>Question:</u></h3>
The present ages of Ram and Rehman are in the ratio 8:9. After 5 years, the ratio of their ages will be 9:10. Find their present ages.
<h3><u>Statement:</u></h3>
The present ages of Ram and Rehman are in the ratio 8:9. After 5 years, the ratio of their ages will be 9:10.
<h3><u>Solution:</u></h3>
- Let the present age of Ram and Rehman be 8x years and 9x years respectively.
- After 5 years, their ages will be 9x years and 10 years respectively.
- Therefore, by the problem

- So, the present age of Ram = 8x years = (8×5) years = 40 years
- The present age of Rehman = 9x years = (9×5) years = 45 years
<h3><u>Answer:</u></h3>
The present ages of Ram and Rehman are 40 years and 45 years respectively.
<h2>Answer</h2>
f(x) = 190(1.15)x
<h2>Explanation</h2>
To solve this, we are going to use the standard exponential function:

Where
is the final price after
years
is the initial price
is the rate in decimal form
is the time in years
We know from our problem that the initial price is $190, so
. Now to convert the rate, 15%, to decimal form, we are going to divide it by 100%, so
. Let's replace the values:
