**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)
