Question
Statements: All numbers are alphabets. All
alphabets are vowel. No vowel is digit. Conclusions:I. No number is digit. II. No alphabet is digit. In each question below are given three statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusion logically follows from the given statements, disregarding commonly known facts. Give answer :Solution
All numbers are alphabets.(A) + All alphabets are vowel(A) ⇒ All numbers are vowel(A) + No vowel is digit(E) ⇒ No number is digit(E). Hence conclusion I follows. All alphabets are vowel (A) + No vowel is digit(E) ⇒ No alphabet is digit(E). Hence conclusion II follows. Alternate method: 
1.3wx = 40 – wy
2. b2 = 2b + p
3. d2 + d = q
Now, observe the given conditions:
One root of equation...
I. 63x2 + 148x + 77 = 0
II. 21y2 + 89y + 88 = 0
I. 3x2 – 17x + 10 = 0
II. y2 – 17y + 52 = 0
What is the average salary of 10 officers , if a clerk’s salary is Rs. 15,000?

The quadratic equation 2x² − kx + 3 = 0 has equal roots. Find k.
If x^2 - 7x + k = 0 has roots that are equal, what is the value of k?
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 22x + 120 = 0
Equation 2: y² - 25y + 144 = 0
I). 4p + 3q = 25
II). 5p + 2q = 26Â
I. x2 + 28x + 96 = 0
II. y2 + 3y - 70 = 0
I. 5q = 7p + 21
II. 11q + 4p + 109 = 0
