Answer:

Smaller number = 29 and larger number = 31.

Explanation:

Let the two consecutive odd numbers be x (smaller number) and x+2 (larger number).

We know that the sum of the larger number (x+2) and twice the smaller number (2x) is equal to 27 less than four times the smaller number (= 4x - 27). So we can write it as:


(x+2)+2x=4x-27

Solving for
x to get:


x+2+2x= 4x-27


3x+2=4x-27


x=29

and
(x+2)= 29+2=31

Therefore the smaller number = 29 and larger number = 31.

The answer is: 29 and 31.

1. Let's call the smaller odd number:
x.

2. Let's call the larger odd number:
x+2

3. Based on the information given in the problem, the sum of the larger number (
x+2) and twice the smaller number (
2x) is 27 less than four times the smaller number (
4x-27).

4. Then, you can write the following expression and solve for
x to find the smaller number:


x+2+2x=4x-27\\2+27=4x-3x\\x=29

5. Therefore, the larger number is:


29+2=31
