The product of three consecutive even numbers is 2688. The product of the first and the second number is 168. What is five times the third number?1). 802). 1003). 604). 70

Answer»

Let, the numbers are = a, a + 2, a + 4

∴ a (a + 2)(a + 4) = 2688 ……….(1)

∴ a (a + 2) = 168 ………..(2)

From (1) and (2) we GET,

⇒ a + 4 = 2688/168

⇒ a + 4 = 16

∴ the third number = 16

∴ Five times the third number = 5 × 16 = 80
