If the point P(6, 2) divides the line segment joining A(6, 5) and B(4, y) in the ratio 3 : 1, then the value of y is :

1. 1

2. 2

3. 3

4. 4

The ratio in which the point P(1, 2) divides the join of the points A(-2, 1) and B(7, 4) is:

1. 1 : 2

2. 2 : 1

3. 3 : 2

4. 2 : 3

In what ratio is the line segment joining the points P(-4, 2) and Q(8, 3) divided by y-axis?

1. 1 : 3

2. 3 : 1

3. 1 : 2

4. 2 : 1
