​Medan and Mohan are standing in a row of people. Madan is standing at the 16^th position from the left side of me row and Mohan is standing at the 19^th position from the right side of the row. If both of them interchange their positions Madam becomes 28^th from the left. How many people are standing in the row?​

 Medan and Mohan are standing in a row of people.

 Madan is standing at the 16^th position from the left side of me row and Mohan is standing at the 19^th position from the right side of the row.

After interchange of positions:
Madan moves to Mohan's position, and his new position becomes the 28th from the left.

Now,

=28+19−1=46

Thus, correct option is (d).
