Answer 1

$\huge\mathfrak\green{Answer:}$

Given:

• We have been given that the sum of three consecutive numbers is 12.

To Find:

• We need to find the consecutive numbers.

Solution:

Let the three consecutive numbers be (x), (x + 1) and (x + 2).

Now it is given that the sum of these consecutive numbers is 12. Therefore,

x + (x + 1) + (x + 2) = 12

=> x + x + 1 + x + 2 = 12

=> 3x + 3 = 12

=> 3x = 12 - 3

=> 3x = 9

=> x = 9/3

=> x = 3

Hence, the consecutive numbers are:

x = 3

x + 1 = 3 + 1 = 4

x + 2 = 3 + 2 = 5

Therefore, option A (3, 4, 5) is the correct answer.
