Remember, any number \(N\) when divided by divisor \(x\) can be written as \(xQ + R\)
Where, Q = quotient and R = remainder
Using the above logic, Number of Presents = \(13Q + 11\)
Let us assume Q = 1 and 10
Number of Presents then could be 24 and 141
Case I: \(P = 24\)
Col. A: on dividing 24 by 14, remainder is 10
Col. B: on dividing 24 by 15, remainder is 9
Col. A > Col. B
Case II: \(P = 141\)
Col. A: on dividing 141 by 14, remainder is 1
Col. B: on dividing 141 by 15, remainder is 6
Col. A < Col. B
Hence, option D
[NOTE: try to pick 2-3 values having a difference of 5-10 in between them]

Remainder theory, but it's time consuming cuz you have to try several values before getting B greater than A.
