    E If the data given in both statements I and II together is not sufficient to answer the question. Correct Answer Incorrect Answer

    Solution

    From Statement I : Let the first number be x.   x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 8 × 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
