(A) 28°

(B) 30°

(D) 40°

View Answer

Ans: B

Angle traced by the minute hand in 5 minutes = $$({360}/{60} × 5)$$ = 30°.

Question: 2

How many times are the hour hand and the minute hand of a clock at right angles during their motion from 1.00 p.m. to 10.00 p.m.?

(A) 10

(B) 18

(D) 24

View Answer

Ans: B

The duration from 1.00 p.m. to 10.00 p.m. is 9 hours and during each of these 9 hours the hands of the clock are at right angles twice.

∴ So, required number = 9 × 2 = 18.

A clock gains 5 minutes in one hour. Therefore, the angle traversed by the minute hand in 1 hour is

(A) 360°

(B) 370°

(D) 390°

View Answer

Clearly, the minute hand traverses 65 minutes in 1 hour.

Required angle = $$({360}/{60} × 65)$$ = 390°.

Question: 4

A watch goes fast by 15 minutes compared to the right time everyday. If it is corrected and set to the standard time at 12 o'clock at noon, which of the following will be the time shown by it at 4 : 00 a.m. in the morning?

(A) 3 : 45 a.m.

(B) 3 : 50 a.m.

(D) 4 : 15 a.m.

View Answer

Ans: C

Time gained in 24 hours = 15 min.

Time gained in 16 hours = $$({5}/ {24} × 16)$$ min = 10 min.

Hence, time shown by the watch at 4 a.m. = 4:10 a.m.
