Clock & Calendars And Data Sufficiency Test - 1

Using the logic, we conclude that if 4:40 which is actually in the south east direction is equivalent to east direction then logically the minute hand which is actually in the south west direction will be equivalent to the south direction. Hence choice (b) is the correct option.

The water image of the clock will be similar to the image created when the object is seen horizontally in the mirror. Hence the corresponding time will be 4:40. Therefore choice (c) will be the correct option.

Using logic, we conclude that if the east becomes north then the north will become west. Based on this logic we can conclude that if the watch shows 3:00 then the minute hand will be in the west direction. Hence, choice (b) will be the answer.

The mirror image time will be 7:30 correspondingly

Every five minutes in a watch are covering 30 degrees therefore, 50 minutes will be catering 300 degrees, therefore choice(d) is the correct option.

The year during this interval was 1998 and it was not a leap year. Now, we calculate the no. of odd days in 1999 up to February 19:

In 1997, December 30 and 31 give 2 odd days

∴ Total number of odd days = 3 + 5 + 1 + 2 = 11 days = 4 odd days.

Therefore, December 30, 1997 was 4 days before Saturday i.e., on Tuesday

Starting with 1987, we go on counting the number of odd days till the sum is divisible by 7.

Number of odd days = 1(1987) + 2(1988) + 1(1989) + 1(1990) + 1(1991) + 2(1992) + 1(1993) + 1(1994) + 1(1995) + 2(1996) + 1(1997) = 14/7 = 0 odd days.

So, the year next to 1987 having the same calendar as that of 1987 is 1998.

X was born on March 3. Being a leap year, Y was hence born on Feburary 28. Since Feburary 26 was a Saturday, Feburary 28 must be a Monday.

2004 was a leap year.

Therefore, number of days from 13th February to 13th April = 16 + 31 + 13 = 60

Number of odd days = 60/7 ⇒ 4

Hence, 4 days after Tuesday ⇒ Saturday.

Statement II is sufficient to answer the question as it says that the train will leave exactly between 4 and 5 pm, meaning the train will leave at 4:30 pm.
