Question

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

Answer 1

Let the three consecutive natural be
x , y and z with x< y < z.

Then
y = x+1

z = y+1

z = (x+1) +1 = x+2

As per given data

5x = 4z + 9

5x = 4(x+2) +9

5x = 4x +8+9

x = 17

Hence the 3 numbers are

17 , 18 , 19
