Answer 1

Answer: (B)

$8.45$ a.m.

Time taken to reach at the stop $=$ $10$ minutes.
Time of reaching at stop $=$ $8.40$ am
$\therefore$ 40 - 10 minutes $=$ $8.30$am
$\therefore$ He started from home at $8.30$ am which is $15$ min earlier than usual.
So he usually leaves at
$\therefore$ $8.30$ am + $15$ minutes $=$ $8.45$ am
