Hemant sir 8917668285

Step-by-step explanation:

Everyday it would lose

(5 seconds * 24 hours) seconds

=120 seconds

= 120/60 minutes

=2 minutes

Till next Wednesday it would lose

(2*7) minutes [ as the same time next week has been given]

=14 minutes

So when it would be actual 6:30 am 14 minutes would be left for the watch to show 6:30 am.

Therefore the time shown by the watch would be 6:(30-14) equivalent to 6:16.

Answer 2

Answer:

The true time is 10:04:00 A.M.

Step-by-step explanation:

Given:

The watch loses 6 second in 10 minutes.

Set time = 10: P.M.

Morning watch time = 7:00 A.M.

Solution:

In 10 minutes ,it looses 6 second

1 minutes = 6/10

= 0.6

Time interval between 10:00 P.M. to 7 A.M. is 9 hours.

9 hours = 540 minutes

1 minutes = 0.6 loses

540 minutes =

$540 \times 0.6$

= 324 minutes

324 minutes = 5 hours 4 minutes

The true time is 10:04:00 AM
