    If 20 + 8 * 5 = e, then find the value of e  < 2 > 4.

    A 2286 Correct Answer Incorrect Answer
    B 2275 Correct Answer Incorrect Answer
    C 2160 Correct Answer Incorrect Answer
    D 2450 Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    20 + 8 * 5 = e ⇒ e =  20² - (8 x 5) = 400 - 40 = 360 e  < 2 > 4 = 360 < 2 > 4 ⇒ (360 x 2) + (360 x 4) = 720 + 1440 = 2160
