Dana and everyone, I still feel that the answer should be C. Can you please help me out here? This is how I solved it. (1) Consider a line DB=7 and a circle around it. Draw the line BE such that BCA=60 degrees. So, without knowing that DE || CA, I can draw a line in many ways. So option 1 is not suf...

I did the same mistake of subtracting both the speeds. Wonder why. Anyways, this method could be faster I guess. Total Distance = 20pi - 20 (B has already traveled) + 12 (Extra 12 miles from Qn) = 20pi - 8. Total Speed = 3 + 2 time = Distance/Speed = 4pi - 1.6 But B has already traveled for 10 hours...

OA is D. My question is, don't you think Caption James Cook is an object. So, we should use WHOM instead of WHO? This is not an active voice sentence. A passive one. The subject is Capt. James Cook. Hence, we use "who". Consider these two sentences: 1. James met Harry. He thought him to b...

So, the number of intersection between a triangle and a circle can be the following numbers: 1: Imagine a triangle tip touching a ci...

This is how I did it.
From sentence 1:
A + B + C = Radio
From sentence 2:
C=2A
From sentence 3:
A = B - C - 70
From sentence 4:
2A + (B-10) + (C-10) = Radio.
From 4 and 1:
2A + (B-10) + (C-10) = A + B + C
You get A = 20.
So, from sentence 2:
C = 40.
From sentence 3:
B = 130.

I remember, Stacey has mentioned in one of the posts that "what" is used as either interrogative pronoun or interrogative adjective.
I could not figure out which one makes sense here.
