Option (a). It is somewhat similar to Q12 at this link

In Δ ABC, if E divides AB in the ration 3:1 and F divides BC in the ratio 3:2, find the ratio of the areas of the Δ BEF and Δ ABC.

P.s in the solution apparently two perpendiculars were drawn from points A and E and these were in the ratio 4:1 (in that order), I still could not comprehend it really. Hope someone can solve this. Thank you

PQRS is a square with side 2a units. A circle of radius a is drawn with P as the centre. Two tangents are drawn from Q and S to the circle which meet at X. Which of the following cannot be the length of XP?

a(root 6 -root 2)
a(root 6 + root 2)
a root 2
any of the above is possible for XP
