At 5 o'clock, the minute hand is 25 min. space behind the hour hand.

Case I: Minute hand is 3 min.spaces behind the hour hand.

In this case, the minute hand has to gain (25 - 3) = 22 minute space 

55 min are gained in 60 min.

22 min. are gained in` (60/55 xx 22)` min. = 24 min

:. The hands will be 3 min. apart at` 31 5/11` min. past 5.

Case II : Minute hand is 3 min.spaces ahead of the hour hand.

In this case, the minute hand has to gain (25 + 3) = 28 minute spaces.

55 min.are gained in 60 min.

28 min. are gained in` (60/55 xx 28)` `= 31 5/11` min.

:. The hands will be 3 min. apart at `31 5/11` min. past 5.

Time from 8 a.m. on Sunday to 8 p.m. on following Sunday

       = 7 days 12 hours = 180 hours.

:. The watch gains `(5 + 5 4/5)` min or `54/5` min. in 180 hrs.

Now` 54/5` min. are gained in 180 hrs.

:. 5 min. are gained in `(180 xx 5/54 xx 5)` hrs.

= 83 hrs 20 min. = 3 days 11 hrs 20 min.

:. watch is correct 3 days 11 hrs 20 min. past 7 p.m.on Wednesday.

:. It will be correct at 20 min.past 7 p.m. on Wednesday.

`:. 356/15` hrs of this clock = 24 hours of correct clock.

89 hrs of this clock` = (24 xx 15/356 xx 89)` hrs hours of correct clock.

   = 90 hrs of correct clock.

So, the correct time is 11 p.m.

Time from 8 a.m. on a day to 1 p.m. on the following day = 29 hrs.

24 hours 10 min.of this clock = 24 hours of the correct clock.

`145/6` hrs of this clock = 24 hrs of the correct clock

29 hrs of this clock` = (24 xx 6/145 xx 29)` hrs of the correct clock

   = 28 hrs 48 min of correct clock

:. The correct time is 28 hrs 48 min. after 8 a.m.

This is 48 min. past 12.

` = Rs.(107 + 1/2) = Rs.215/2.`

 Cash required to purchase Rs. 3200 stock
