Question
Direction: In the given question a statement is
followed by two conclusions numbered I and II. You have to assume everything in the statement to be true, then consider the two conclusions together and decide which of them logically follows beyond a reasonable doubt from the information given in the statement. Statement: All alphabets are numbers All numbers are vowels Few numbers are letters Conclusion: I. Some alphabets are vowels II. Some vowels are lettersSolution
All alphabets are numbers (A) + All numbers are vowels (A) → All alphabets are vowels (A) → I.I. → Some alphabets are vowels (I). Hence conclusion I follows. Few numbers are letters → Conversion → Some letters are numbers (I) + All numbers are vowels (A) → Some letters are vowels (I) → Conversion → Some vowels are letters (I). Hence conclusion I follows.
- Suppose both the roots of q² + kq + 49 = 0 are real and equal, then determine the value of 'k'.
I. 84x² - 167x - 55 = 0
II. 247y² + 210y + 27 = 0
l). 2p² + 12p + 18 = 0
ll). 3q² + 13q + 12 = 0
I. 2x² - 9x + 10 = 0
II. 3y² + 11y + 6 = 0
I. 6x2 - 47x + 77 =0
II. 6y2 - 35y + 49 = 0
I. 12a2 – 55a + 63 = 0
II. 8b2 - 50 b + 77 = 0
...I. 2y2 – 19y + 35 = 0
II. 4x2 – 16x + 15 = 0
I. 5x² - 24 x + 28 = 0
II. 4y² - 8 y - 12= 0
In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer
I. x2 – ...
I.8(x+3)+ 8(-x)=72
II. 5(y+5)+ 5(-x)=150
