Explanation

To find the duration of the train journey, subtract the start time from the arrival time:

Arrival time: 5:23 p.m.

Start time: 9:32 a.m.

Convert both times to a 24-hour clock:

Arrival time: 17:23 (5:23 p.m.)

Start time: 09:32 (9:32 a.m.)

Subtract the start time from the arrival time:

17:23 - 09:32 = 7 hours 51 minutes

Therefore, the train journey took 7 hours and 51 minutes.

The alphabets follow a pattern:

$C+2=E$

$E+3=H$

$H+4=L$

$L+5=Q$

$Q+6=W$

$W+7=D$

Hence, $D$ replaces the question mark.

Explanation

If 8 men eat 16 mangoes in 15 minutes, it means each man eats 16/8 = 2 mangoes in 15 minutes.

So, in 30 minutes, each man will eat 2×2 = 4 mangoes.

Therefore, if there are 16 men eating for 30 minutes, they will eat 16×4 = 64 mangoes.
