Question
From the following letters, select the sixth and
fourteenth letters from your right and select the fifth and twentieth letter from your left and form a meaningful word. ABCDEFGHIJKLMNOPQRSTUVWXYZ Which of the following options is correct regarding that word?Solution
Given letters: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 6th and 14th letter from the right is U and M . The 5th and 20th letters are E and T . So, the letters are U, M, E, T. The meaningful word can be formed from U, M, E, T is MUTE . Hence, "M is the first letter of that word" is the correct answer.
I. 15y2 + 26y + 8 = 0
II. 20x2 + 7x – 6 = 0
I. x2 – 10x + 21 = 0
II. y2 + 11y + 28 = 0
- If the quadratic equation x² + 18x + n = 0 has real and equal roots, what is the value of n?
I. 35x² - 24x – 35 = 0
II. 72y² - 145y + 72 = 0
I. 2x2 – 5x – 12 = 0
II. 2y2 + 13y + 20 = 0
I. 22x² - 97x + 105 = 0
II. 35y² - 61y + 24 = 0
I. 4x2 + 3√7 x-7 =0
II. 7y2 + 4√7 y-5=0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 11x² - 93x + 88 = 0
Equation 2: 13y² + 118y + 93 = 0
I. 5x² - 28x + 39 = 0
II. 2y² - 13y + 20 = 0
I. 4x2 + 9x - 9 = 0
II. 4y2 - 19y + 12 = 0
