Answer: (b)

Total no. of days between 27.3.1995

and 1.11. 1994 = 27 + 28 + 31 + 31 + 29 = 146

Now, 146 is not completely divided by 7. It we have one day more then we have 147 days which is completely divided by 7. Thus, the days of the week on 1 Nov, 1994 was Monday. But the day will be Tuesday ( We have 146 days)

Answer: (c)

Angle made by hour hand for 12 hours = 360°

Angle made by hour hand for 1 hour = ${360°}/{12}$

∴ Angle made by hour hand for 6 hours = ${360°}/{12}$ × (6) = 180°

Answer: (c)

First clock will gain 11 × 2 minutes in 11 hrs., and second clock will lose 11 × 1 minutes in 11 hrs.

Hence difference will be 33 minutes.

Answer: (d)

55 min. spaces are covered in 60 min.

60 min. spaces are covered in $({60}/{55} × 60)$ min. 65 $5/{11}$ min.

Loss in 64 min. = $(65 {5/{11}} - 64)$ min. = ${16}/{11}$ min.

Loss in 24 hrs. $({{16}/{11}} × {1/{64}} × 24 × 60)$ min. 32 $8/{11}$ min.

Answer: (a)

At 5 o'clock, the hands are 25 min. spaces apart.

To be at right angles and that too between 5.30 and 6, the minute hand has to gain (25 + 15) = 40 min. spaces 55 min. spaces are gained in 60 min.

40 min. spaces are gained $( {60}/{55} × 40)$ min = 43 $7/{11}$ min

∴ Required time = 43 $7/{11}$ min. past 5
