If a person is seventh from the beginning in a row and eleventh from the last, how many persons are there in the row?
A
17
B
16
C
14
D
11
Correct Option:
A
Explanation
If a person is 7th from the beginning and 11th from the end, that person is counted in both figures. Hence the total number of persons is 7 + 11 − 1 = 17. The subtraction of 1 prevents double-counting the same person.
