Few people are standing in a row. Sneha is at the 17th position from the front, and Alisha is standing at the 7th position from the back.
If Sneha and Alisha interchange their positions, Alisha becomes 12th from the back. How many people are there in the row?
~~~~~~~~~~~~~~~~~~
If you read the condition ATTENTIVELY, you will see that there are 16 positions before #17 and 11 after #17.
So, there are 16 + 1 + 11 = 28 people in the line.
Answer. There are 28 people in the line.
---------------
P.S. This part of the condition " . . . Alisha is standing at the 7th position from the back." is EXCESSIVE, NON-NECESSARY and is not used in the solution.
It is included to the condition with the only goal to confuse the reader by giving him non-relevant info.
