Concept:  The question tests on Geometry(Triangles)


This is a pieces of a puzzle type of question, where we need to find an actual value

Statement 1: y = 2x

We do not have any specific information about x nor about the type of triangle.

Therefore Statement 1 Alone is Insufficient. Answer options could be B, C or E.

Statement 2: DCA = 30

Again we do not have any information about the type of triangle, DCA is ,nor any information about any other angles.

Therefore Statement 2 Alone is Insufficient. Answer Options could be C or E

Combining Both Statements:

Same as the 2 statements. There is nothing that we can infer even after combining the 2 statements.

Therefore Both Statements together are Insufficient.

 Option E
