Question

    If the average number of unsold items by company 'B' and

    'D', together, who were presented in a competition is 'a', then find the value of 90% of 'a'.
    A 210 Correct Answer Incorrect Answer
    B 270 Correct Answer Incorrect Answer
    C 300 Correct Answer Incorrect Answer
    D 240 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    For company 'A': Total number of items manufactured = 500 Number of items sold = 260 So, number of unsold items = 500 - 260 = 240 Similarly, 'a' = (280 + 320) ÷ 2 = 300 So, required value = 0.9 x 300 = 270
