Answer 1

3:30 is the correct answer

Answer 2

Answer:

In an hour, minute hand is 55 min spaces ahead of hour hand

So min hand takes (60/55) = (12/11)min to go ahead of hours hand by 1 minute space....

at 3 O'clock hours hand will be at minute space 15 and min hand at 0.

To be ahead of 4 minute spaces than hours hand, min hand need to move (15+4) minute spaces.

For 1 minute space >> 12/11 min

For 19 minute spaces >>(19*12)/11 min = 20 8/11 min

Hence @ 3:20 8/11 min minute hand will be 4 minute spaces ahead of hours hand.
