Question
NUQM is related to PWSO in a certain way based on the
English alphabetical order. In the same way, JQMI is related to LSOK. To which of the following is FMIE related, following the same logic?Solution
Shift each letter two places forward in the alphabet.
F(6)→H(8), M(13)→O(15), I(9)→K(11), E(5)→G(7).
So FMIE → HOKG .
- For what value of a does the quadratic equation x² + ax + 81 = 0 have real and identical roots?
I. 88x² - 13 x – 56 = 0
II. 15 y² + 41 y + 28 = 0
If a and b are the roots of x² + x – 2 = 0, then the quadratic equation in x whose roots are 1/a + 1/b and ab is
I. 6x2 – 7x - 20 = 0
II. 3y2Â - y - 14 = 0
I. 2y2 + 13y + 15 = 0
II. 2x2 + 11 x + 12 = 0
I. 7x² + 27x + 18 = 0
II. 19y² - 27y + 8 = 0
I. x² + 11x + 24 = 0
II. y² + 17y + 72 = 0
I. 24x² - 58x + 23 = 0
II. 20y² + 24y – 65 = 0
 If x satisfies x² – 14x + 40 = 0, find x.
I. 2x2 – 5x – 12 = 0
II. 2y2 + 13y + 20 = 0
