Question
Four of the following five pair of letter cluster are
alike in a certain manner and one is different. Select the one which is different.Solution
The logic followed here is as follows: In each letter cluster from the left end, The 2nd letter is the 2nd succeeding letter of the 1st letter and the 3 rd letter is the 4th succeeding letter of the 2nd letter as per the English alphabetical series. In option 'A', M + 2 = O, O + 4 = S In option 'B', P + 2 = R, R + 4 = V In option 'C', T + 2 = V, V + 4 = Z In option 'D', R + 2 = T, T + 4 = X In option 'E', N + 2 = P, P + 4 = T ≠ U
- 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
