Data Sufficiency

Hi Sanju

I got the Question right but the language of the question is confusing, for instance, one can easily think of three cities to be anywhere in space i.e city C can lie not the the same road. You need to specifically mention that the three cities are co linear.

I too me 2 min to try to solve and finally i solve it keeping that the cities would be co linear.

Correct me if i m wrong here.

How far in miles is city A from city B?
I. City A is 50 miles away from city C, whereas city B is 30 miles away from city C.
II. City A is 10 more miles far from city C as it is from city B.


Initially, even I was not convinced with the answer choice C because of the directions...

After sanju09's explanation, I got it easily...

Thank You Sanju09...

Since no city can hang in air, hence we can easily understand that the three cities are to be taken in a plane, and three distinct points in a plane are not always collinear, otherwise we'd never be able to have a triangle, just as the right angled triangle found in the given question, in the end.
