Question
What is the smallest number of the six numbers?
Statement I: The average of six consecutive odd numbers is 8. Statement II: The sum of six consecutive odd numbers is 48. Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer –Solution
From Statement I: Let the first number be x. x + (x + 2) + (x + 4) + (x + 6) + (x + 8) + (x + 10) = 8 x 6 ⇒ 6x + 30 = 48 ⇒ 6x = 48 – 30 ⇒ 6x = 18 x = 3 From Statement II: Let the first number be x. x + (x + 2) + (x + 4) + (x + 6) + (x + 8) + (x + 10) = 48 ⇒ 6x + 30 = 48 ⇒ 6x = 48 – 30 ⇒ 6x = 18 x = 3
