Question

Of the three consecutive natural numbers, five times the smallest number is 9 more than four times the greatest number, find the numbers

Solution

Let the three conescutive natural number be x, x + 1, x + 2.
From the given information,

5(x) = 4 (x + 2) + 9

⇒ 5x = 4x  +8 + 9

⇒ 5x - 4x = 17

⇒ x = 17

∴ The three consecutive natural numbers are 17, 17 + 1, 17 + 2.
Hence, the three consecutive natural numbers are 17, 18, 19.

  Is there an error in this question or solution?
