The eccentricity of the ellipse with centre at the origin which meets the straight line `x/7 + y/2 = 1` on the axis of x and the straight line `x/3 - y/5 = 1` on the axis of y and whose axes lie along the axes of coordinates, is

The eccentricity of an ellipse with centre at the origin which meets the straight line (x)/(7)+(y)/(2)=1 on the axis of x and the straight line (x)/(3)-(y)/(5)=1 on the axis of y and whose axes lie along the axes of coordinates is

The eccentricity of the ellipse which meets the straight line x//7+y//2=1 on the axis of x and the straight line x//3-y//5=1 on the axis of y and whose axes lie along the axes of coordinates, is

The eccentricity of the ellipse which meets the straight line x/7+y/2= 1 on the x- axis and the straight line x/3-y/5=1 on the y-axis and whose axis lie along the axis of coordinate

The eccentricity of the ellipse which meets the straight line (x)/(7)+(y)/(2)1 on the x -axis and the straight line (x)/(3)-(y)/(5)=1 on the y -axis and whose axis lie along the axis of coordinate

The eccentricity of the ellipse which meets the straight line (x)/(7)+(y)/(2)=1 on the -axis and (x)/(3)-(y)/(5)=1 on the y -axis and whos axis lie along the axes of coordinates is

The eccentricity of the ellipse which meets the straight line (x)/(7)+(y)/(2)=1 on the -axis and (x)/(3)-(y)/(5)=1 on the y -axis and whos axis lie along the axes of coordinates is

The eccentricity of the ellipse which meets the straight line (x)/(7)+(y)/(2)=1 on the -axis and (x)/(3)-(y)/(5)=1 on the y -axis and whos axis lie along the axes of coordinates is

An ellipse meets the line x/7 + y/2 = 1 on the X-axis, and the line x/3-y/5 = 1 on the Y-axis. If its principle axes lie along the co-ordinate axes , find its eccentricity.
