The answer to your question is D
Equation of an ellipse
→having center (0,0) , vertex (
and covertex
and focus
is given by:

As definition of an ellipse is that locus of all the points in a plane such that it's distance from two fixed points called focii remains constant.
Consider two points (a,0) and (-a,0) on Horizontal axis of an ellipse:
Distance from (a,0) to (c,0) is = a-c = 
Distance from (-a,0) to (c,0) is = a + c = 
a -c + a +c
= a + a
= 2 a →(Option A )
25/27 = 0.925925925...
It's almost equal to 1 and it turns out that 1 is 100%.
So, we'd say that it's equal to:
92.59% (to 2 decimal places)
We've multiplied the value above (25/27) by 100.
