Quantitative Aptitude – Geometry – Coordinate – The points (2, 5) and (6, 3)

Quantitative Aptitude – Geometry – Coordinate

Question

The points (2, 5) and (6, 3) are two end points of a diagonal of a rectangle. If the other diagonal has the equation y = 3x + c, then c is

A) -5
B) -6
C) -7
D) -8

Answer

Option (D)

Solution

From CAT 2017 – Quantitative Aptitude – Geometry – Coordinate, we can see that,
The diagonals of a rectangle bisect each other. Mid points of the diagonal are (4,4)
These points fall on the line with equation y = 3x + c
Putting the coordinates (4,4) in the equation, we get
c= -8
Option (D)
