The age of Sita is five years more than Gautam's age. 5 years ago, the ratio of their ages was 3:2. Find their present ages.
<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>The age of Sita = (x + 5) years.
And, the age of Gautam = x years.
Now,
5 years ago, the ratio of their ages was 3 : 2
Now by cross multiplying, we get,
3x = 2(x + 5)
3x = 2x + 10
3x - 2x = 10
<h3>x = 10 </h3>Hence, the age of Sita = (x + 5) = (10 + 5) = 15 years.
And, the age of Gautam = x = 10 years.
Now,
The present age of Sita = 15 + 5 = 20 years. (Answer)
And, the present age of Gautam = 10 + 5 = 15 years. (Answer)
Answer:

Given
Represent the normal temperature with N and today's temperature with T.
Such that:
Required
Determine the temperature above the normal temperature
The interpretation of this is to calculate the difference between Bill's normal temperature and Bill's today temperature.
Represent the difference with D
D is calculated as follows:
Substitute values for T and N
Hence, today's temperature is 5.7 degrees above Bill's normal temperature.
