Question

The sum of 3 consecutive even numbers is 90.Find the numbers

Answer 1

Answer:

Let the numbers be x ,x+2 and x+4

According to the question

x+x+2+x+4=90

3x+6=90

3x=84

x=28

x+2=28+2=30

x+4=28+4=32

So, the three consecutive positive even integers are 28,30 and 32

Step-by-step explanation:

Answer 2

Answer:

Let the three consecutive even numbers be (2x), (2x + 2),(2x+4) . Then,

$2x + ( 2x +2)+(2x+4) = 90 \\ = > 6x + 6 = 90 \\ = > 6x = 90 - 6 \\ = > 6x = 84 \\ = > x = \dfrac{84}{6 } = 14$

So, the required numbers are

2 × 14, 2 × 14 +2 , 2 × 14 +4 .

The numbers are :-

28,30 and 32
