Explanation:-
Answer: Option A. -> 2 min 52 s past 10Answer: (a)
Total time from 3 O' clock Sunday afternoon to 10 O' clock Tuesdy morning = 43 h
Total increased time = 12/3 × 43 = 172s = 2 min 52s
Therefore, Time at 10 O' clock Tuesday morning = 2 min 52 s past 10
Explanation:-
Answer: Option B. -> 11 pmAnswer: (b)
Time from 5 am of a particular day to 10 pm on the 3rd day is 89 h.
Now, the clock loses 16 min in 24 h or in other words,
we can say that 23 h 44 min of this clock is equal to 24 h of the correct clock.
$(23 + 44/60) = 356/15$ h of this clock = 24h of the correct clock
Therefore, 89 h of this clock = $(24 × 15 / 356 × 89) h$
the correct clock = 90 h of the correct clock or 89 h of this clock = 90 h of the correct clock.
Therefore, it is clear that in 90 h this clock loses 1 h and hence, the correct time is 11 pm when this clock shows 10 pm.
Explanation:-
Answer: Option B. -> 2 pm on WednesdayAnswer: (b)
Time from Monday noon (12 pm) to 2 pm the following Monday = 7 days 2 h = 170 h
Now, the watch gains (2 + 4 4/5) min from Monday (12 pm) to 2 pm,
the following Monday. In other words, the watch gains 34/5 min in 170 h.
Therefore, it will gain 2 min in (170 × 5/34 × 2) = 50 h = 2 days 2 h
Therefore, the watch is correct after 2 days 2 h from Monday noon or at 2 pm Wednesday.
