JEE Math Practice Question
The parabolas $${y^2} = 4x$$ and $${x^2} = 4y$$ divide the square region bounded by the lines $$x=4,$$ $$y=4$$ and the coordinate axes. If $${S_1},{S_2},{S_3}$$ are respectively the areas of these parts numbered from top to bottom ; then $${S_1},{S_2},{S_3}$$ is :
- A.$$1:2:1$$
- B.$$1:2:3$$
- C.$$2:1:2$$
- D.$$1:1:1$$
