C - 3 hrs 30$\frac{8}{11}$ min

D - 3 hrs 32$\frac{8}{11}$ min

Answer : D

Explanation

( 5n + 15) × $\frac{12}{11}$, here n = 3 therefore we get 32$\frac{8}{11}$ min past 3.

Answer : B

Explanation

It is clear that to coincide together the minute hand has to travel through 30 minute space.

Therefore required time = 30 × $\frac{60}{55}$ = 32$\frac{8}{11}$ minute past 6

Q 3 - A clock shows 10 O `clock in the morning. How many degrees will the hour hand rotate when the clock shows 4 O` clock in the afternoon?

A - 144o

B - 150o

C - 168o

D - 180o

Answer : D

Explanation

Angle turned in 6 hrs = $\frac{360}{12}$ × 6 = 180o

Answer : A

Explanation

(5n±8) × $\frac{12}{11}$; n = 8

$\frac{574}{11}$ min. past 8, $\frac{384}{11}$ min past 8

Q 5 - If two hands are at 15o, they are 15 min space apart. It happens how many times in every 1 hour?

A - Once

B - Twice

C - Thrice

D - None of these

Answer : C

Explanation

Two Hands

Answer : B

Explanation

(5n ± 15) × $\frac{12}{11}$ min past 6, here n = 6

Therefore 49$\frac{1}{11}$ min past 6 and 16$\frac{4}{11}$ min past 6

Q 7 - What should be the time difference from 4.20 am to 7 .30 pm on the Sunday?

A - 15.00 hours
