Question

The sum of three consecutive multiples of 4 is 444. The multiples are ____ , ____ and _____ .

• A. 144, 148, 152
• B. 100, 104, 108
• C. 148, 152, 156
• D. 152, 156, 160

Answer 1

The correct option is A

144, 148, 152

If x is a multiple of 4, the next multiple is x + 4, next to this is x + 8

According to the question,

x + (x + 4) + (x + 8) = 444

⇒ 3x + 12 = 444

⇒ 3x = 432

⇒ x = 144

x + 4 = 144 + 4 = 148

x + 8 = 144 + 8 = 152

Therefore the multiples are 144, 148, 152
