    Question

    Directions (Q.26-30): In a certain instruction system the different computational processes are written as follows: a) P @ Q # R: means “sum of Q and R is subtracted from the cube of P.   b) P + Q * R: means “product of Q and R is subtracted from the square of P.   c) P < Q > R: means “Product of P and Q is added to product of P and R.   d) P $ Q % R: means “P percent of Q is added to  R.

    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
