    Question

    Directions (Q.21-25): In the following questions, two equations numbered I and II are given. You have to solve both the equations and find out the correct option. Give answer

    I. 821

    > x x² - 757 x² = 256 II. √196 y³ - 12 y³ = 16
    A If x ≥y Correct Answer Incorrect Answer
    B If x ≤y Correct Answer Incorrect Answer
    C If x>y Correct Answer Incorrect Answer
    D If x Correct Answer Incorrect Answer
    E If x=y or relationship between between x and y cannot be established Correct Answer Incorrect Answer

    Solution

    I. 821 x ² - 757 [if gte msEquation 12]> x [if !msEquation]--> [endif]-->x² = 256 [if gte msEquation 12]>⇒ [if !msEquation]--> [endif]-->64 x ² = 256 [if gte msEquation 12]>⇒ [if !msEquation]--> [endif]--> x ² = 4 [if gte msEquation 12]>⇒ [if !msEquation]--> [endif]-->, [if gte msEquation 12]>x [if !msEquation]--> [endif]-->x = `+-` 2 II. √196 y [if gte msEquation 12]>y [if !msEquation]--> [endif]-->³ - 12 [if gte msEquation 12]> y [if !msEquation]--> [endif]-->y³ = 16 [if gte msEquation 12]>⇒ [if !msEquation]--> [endif]-->14 y ³ - 12 [if gte msEquation 12]>y [if !msEquation]--> [endif]-->y³ = 16 [if gte msEquation 12]>⇒ [if !msEquation]--> [endif]-->2 y ³ = 16 , y [if gte msEquation 12]>⇒ [if !msEquation]--> [endif]--> = 2 Hence, x `<=` y
