Answer» e 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 = 3Hence, the consecutive numbers are:x = 3x + 1 = 3 + 1 = 4x + 2 = 3 + 2 = 5Therefore, option A (3, 4, 5) is the correct answer. |
