The ratio in which the line segment joining the points (5, -2) and  (0, 7) is divided by the point (53,4) \left( \frac{5}{3}, 4 \right)(35​,
Question

The ratio in which the line segment joining the points (5, -2) and  (0, 7) is divided by the point (53,4) \left( \frac{5}{3}, 4 \right)​ is:

A.

1 : 2

B.

1 : 3

C.

2 : 1

D.

3 : 2

Correct option is C

Given::
A = (5, -2)
B = (0, 7)
Point dividing AB: P = (5/3, 4)
​Concept used :
Using the section formula:
If a point P(x, y)  divides the line joining  A(x1,y1)A(x_1, y_1) ​ and  B(x2,y2)B(x_2, y_2)​ in the ratio } m:n, then:}
x=mx2+nx1m+n,y=my2+ny1m+nx = \frac{mx_2 + nx_1}{m + n}, \quad y = \frac{my_2 + ny_1}{m + n} \\​​
Solution:
x=m0+n5m+n=5nm+n=53=>5nm+n=53=>nm+n=13=>3n=m+n=>2n=m=>mn=21x = \frac{m \cdot 0 + n \cdot 5}{m + n} = \frac{5n}{m + n} = \frac{5}{3} \\\Rightarrow \frac{5n}{m + n} = \frac{5}{3} \Rightarrow \frac{n}{m + n} = \frac{1}{3} \\\Rightarrow 3n = m + n \Rightarrow 2n = m \Rightarrow \frac{m}{n} = \frac{2}{1} \\​​
Correct answer is (c) 2 : 1
