Question

The sum two consecutive multiple of 3 is 429. Find the numbers..........3x, 3x+3

Answer 1

Let the two consecutive multiple of 3 be 3x and 3x+3 respectively

According to the question

3x+3x+3=429

6x=429-3

6x=426

x=426/6

x=71

First number = 3x= 3×71=213

Second number =3x+3=213+3=216

Therefore, two consecutive multiple of 3 are 213 and 216
