So, after 63 days, it will be Monday.

∴ After 61 days, it will be Saturday.

Answer: (a)

Next train for N. Delhi leaves at 8:30 p.m. Since time interval between two trains for N. Delhi is 45 minutes. A train for New Delhi has left 15 minutes ago.

Time of information = 8:30 – 45 + 15 = 8 P.M.

Answer: (b)

In one hour, hour hand and minute hand are at right angles 2 times.

Time = 10 p.m – 1 p.m = 9 hr.

∴ No. of times, when both hands are perpendicular to each other in 9 hr = 9 × 2 = 18

Answer: (a)

Here H × 30 = 4 × 30 = $120^0$.

(Since initially the hour hand is at 4. ∴ H = 4).

Required angle A = 900 and since, H × 30 > A° so, there will be two timings.

Required time T = $2/{11}$ (H × 30 ± A) minutes past H.

∴ One timing = $2/{11}$ (4 × 30 + 90) minutes past 4

= 38 $2/{11}$ minutes past 4. Or 4 : 38 approx.

Answer: (a)
