उत्तर
The co-ordinates of a point which divides the line segment joining the points (3, 5) and (8, 10) in the ratio 2 : 3, are (5, 7).
Explanation:
By the section formula for internal division in the ratio 2 : 3,
⇒ x = (2 × 8 + 3 × 3) / (2 + 3)
= `25/5`
∴ x = 5
⇒ y (2 × 10 + 3 × 5) / 5
= `35/5`
∴ y = 7
