प्रश्न

The sum of three consecutive even numbers is 54. Find the numbers.

योग

उत्तर

Let the first even number = x

second even number = x + 2

and third even number = x + 4

According to the condition,

x + x + 2 + x + 4 = 54

⇒ 3x + 6 = 54

⇒ 3x = 54 – 6

⇒ x = `48/3 = 16`

∴ First even number = 16

Second even number = 16 + 2 = 18

and third even number = 16 + 4 = 20
