If the sum of two consecutive numbers is 71 and one number is x, then the other number is:

I. x + (x + 1) = 71

II. x + (x + 2) = 71

III. x + x = 71

IV. none of these

Answer :

Final answer:

To find the other number when the sum of two consecutive numbers is given, we can use the equation x + (x+1) = 71. Solving this equation will help determine the value of x and the other number. The correct option is (I) x + (x+1) = 71.

Explanation:

If the sum of two consecutive numbers is 71 and one number is x, then the other number is:

  1. (I) x + (x+1) = 71
  2. (II) x + (x+2) = 71
  3. (III) x + x = 71
  4. (IV) none of these

To solve this problem, we can use the equation x + (x+1) = 71. This equation represents the sum of two consecutive numbers, with x representing the first number. By solving this equation, we can find the value of x and then determine the other number.

Step-by-step solution:

x + (x+1) = 71

2x + 1 = 71

2x = 70

x = 35

So, the other number is x+1, which is 35+1 = 36.
