    2pm on Wednesday


    Time from 12 p.m. on Monday to 2 p.m. on the following Monday = 170 hours (7 days 2 hours).
    The watch gains 34/5 minutes in 170 hrs
    Now, 34/5 minutes are gained in 170 hrs
    2 min are gained in (170*5/34*2) hrs = 50 hrs

    Watch is correct 2 days 2 hrs. after 12 p.m. on Monday i.e., it will be correct at 2 p.m. on Wednesday

    The answer is 2pm on Wednesday.

    Explanation:
    Time from Monday noon (12 o' clock) to following Monday 2 pm

    = 7 day 2 hours

    = 7 × 24 + 2

    = 168 + 2 = 170 hours.

    Total time gained from Monday noon (12 o' clock) to following Monday 2 pm

    = 2 min + 4 min 48 sec = 6 min 48 sec

    The given watch gains 34/5 mins in 170 hours.

    Given that the said watch was 2 minutes low at Monday noon. Hence when it gained 2 minutes, the time was correct.

    The given watch gains 34/5 mins in 170 hours.

    The given watch gains 2 mins in 170 × (5/34) × 2 hours

    = 5 × 5 × 2 hours = 50 hours

    Hence the time was correct after 50 hours from Monday noon

    = after 2 days 2 hours from Monday noon

    = 2 pm on Wednesday

    Time from 12pm on Monday to 2 p.m on the following monday=7 days 2 hours =170 hours.
    ∴ The watch gains (2+4⅘)min. or
    34/5 min. in 170 hrs.

    Now, 34/5 min. gained in 170 hrs.
    ∴ 2 min. are gained in (170× 5/34 ×2)hrs=50hrs
    ∴ Watch is correct 2 days 2 hrs. After 12p.m on Monday i.e., it will be correct at 2 p.m on Wednesday.
