Question

In the question, two quantities I and II are given. You have to solve both the quantities to establish the correct relation between Quantity-I and Quantity-II and choose the correct option. Quantity-I: Find the value of ‘x’ from the equation: x² - 13x + 40 = 0. Quantity-II: Find the value of ‘y’ from the equation: y² - 9y + 20 = 0.

Quantity I x - 13x 40 0 Or, x - 8x - 5x 40 0 Or, xx - 8 - 5x - 8 0 Or, x - 5x - 8 0 Or, x 5, 8 So, Quantity I 5, 8 Quantity II y - 9y 20 0 Or, y - 5y - 4y 20 0 Or, yy - 5 - 4y - 5 0 Or, y - 4y - 5 0 Or, y 4, 5 So, Quantity II 4, 5 On comparing x and y When x 5, y 4 x y When x 5, y 5 x y When x 8, y 4 x y When x 8, y 5 x y Therefore, Quantity I Quantity II Hence, the correct answer is E.
