Question
On which of the following floor does V live?
Answer the questions based on the information given below. Eight persons viz. U, V, W, X, Y, Z, A and B are living in an eight-storey building, but not necessarily in the same order. The bottommost floor is numbered as 1 and the floor immediately above it is numbered as 2 and so on. Not more than one person lives on the same floor. The consecutive alphabetically named person doesn’t live on the adjacent floors of the building. Y lives on an odd-numbered floor and three floors below Z. A lives between Y and Z. Only two persons live between A and B who doesn’t live on the bottommost floor. X lives on an even-numbered floor. The number of floors above X is the same as the number of floors below U. W lives three floors below V.Solution
Y lives on an odd-numbered floor and three floors below Z. A lives between Y and Z. Only two persons live between A and B who doesn’t live on the bottommost floor. X lives on an even-numbered floor. The number of floors above X is the same as the number of floors below U. W lives three floors below V. The consecutive alphabetically named person doesn’t live on the adjacent floors of the building. Hence, cases 1 and 3 get eliminated.
What will be the product of smaller roots of both equations.Â
I. 15y2 + 4y – 4 = 0
II. 15x2 + x – 6 = 0
I). p2 + 17p - 234 = 0
II). q2 - 21q + 108 = 0
I. 6x² - 49x + 99 = 0
II. 5y² + 17y + 14 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 41x + 400 = 0
Equation 2: y² - 41y + 420 = 0
I. 6x2 - 41x+13=0
II. 2y2 - 19y+42=0
I. 64x2 - 64x + 15 Â = 0 Â Â Â Â
II. 21y2 - 13y + 2Â =0
- What should be the value of t in the equation x² + tx + 64 = 0 so that it has two equal real roots?
I. x2 - 17x + 70 = 0
II. y2 - 11y + 28 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 13x² - 60x + 47 = 0
Equation 2: 17y² - 80y + 63 = 0
