*The average of five conservative odd numbers is 84% of the highest number. what is the sum of the first two of these numbers??
Answers
Answer:
The first two numbers are 17 and 19 and their sum is 36.
Step-by-step explanation:
Let the five odd numbers be a, a+2, a+4, a+6 and a+8. Hence, their sum equals 5a + 20 and their average is a+4.
As given in the question,
= > (a+4)/(a+8) = 84/100 = 21/25
Therefore, 25a + 100 = 21a + 168
Or, 4a = 68
Hence, a = 17
Hence,
The first two numbers are 17 and 19 and their sum is 36.
