Question

Find three conescutive whole numbers whose sum is more than 45 but less than 54.

Solution

Let the three conescutive whole number be x, x + 1, x + 2.

From the given information,

45 < x + (x + 1) + ( x + 2) and x + (x + 1)  + (x + 2) < 54

45 < 3x + 3 and 3x + 3 < 54

42 < 3x and 3x < 51

14 < x and x < 17

x = 15,16

If x = 15,
∴ The other two numbers are 16 and 17.
If x = 16,
∴ The other two numbers are 17 and 18.
Hence, three conescutive whole numbers are 15, 16, 17 or 16, 17, 18.

  Is there an error in this question or solution?
