Answer:
Step-by-step explanation:Solution
Let us assume the three consecutive odd numbers of series to be x,x+2 and x+4.
So, the sum of the consecutive odd numbers = 27
Hence
27=x+x+2+x+4
3x+ 6 = 27
3x = 27-6
3x = 21
x = 21/3
x = 7
Other two numbers
x+2 = 7+2 = 9
x+4=7+4=11
So the three numbers are 7 , 9 and 11.
Answer
The three consecutive odd numbers whose sum is 27 are 7, 9 and 11.
