Solution

The correct option is **A** between 1 and 2

Time at which Alex reach back home = 07:15 + 6 hours and 47 minutes

let us first add 6 hours

= 07:15 + 6

= 13: 15

in 12 hour clock,

13 - 12 = 01,

13:15 = 01:15 P.M.

Now let us add 47 minutes

15 + 47 = 62

We know 60 minutes is 1 hour

So the time will be

= 1:15 + 47 minutes

= 2:00 + 2 minutes

= 2:02

for 2 minutes the minute hand will be between 1 and 2.
