A - 12 O`clock

B - 9 pm

C - 11 pm

D - 2 pm

Answer : A

Explanation

$\left ( 24 \times \frac{15}{356} \times 89 \right )$ hrs = 90 hrs of correct clock, correct time will be mid night.

Q 2 - At what time between 7 and 8 O` clock will the hands of a clock be in the same straight line but not together?

A - 5 min. past 7

B - 5 $\frac{3}{11}$ min. past 7

C - 5 $\frac{2}{11}$ min. past 7

D - 5 $\frac{5}{11}$ min. past 7

Answer : D

Explanation

$\frac{60}{55}$ × 5 = 5$\frac{5}{11}$ min. past 7

Q 3 - What is the exact time between 10 and 11 O`clock when the hands are at right angle to each other?

A - 5$\frac{5}{11}$ minute past 11

B - 50$\frac{5}{11}$ minute past 10

C - 40$\frac{5}{11}$ minute past 10

D - 15$\frac{5}{11}$ minute past 10

Answer : A

Explanation

We know that the hands of a clock are always 15 minute space apart when they are in right angle to each other. From figure it is clear that to be at right angle, minute hand must move 5 minute space more.

Minute Hand

We know that minute gained by minute hand in one minute = $\frac{12}{11}$

Therefore 5 minute can be gained in 5 × $\frac{12}{11}$ = 5$\frac{5}{11}$ minute past 10

Answer : C

Explanation

(5n ± x) × $\frac{12}{11}$ min past n.

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

= 33$\frac{9}{11}$ min past 5 and 19$\frac{12}{11}$ min past 5

Q 5 - When two hands are in opposite direction then they are apart by how many minutes?

A - 60 min

B - 45 min

C - 30 min

D - none of these

Answer : C

Explanation

Generally the two hands are always 30 min spaces apart

Two Hands Opposite Direction

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 - At what time between 3.30 and 4 O`clock will the hands of a clock be at right angle?

A - 32$\frac{8}{11}$ minute past 3

B - 45$\frac{8}{11}$ minute past 3

C - 35$\frac{8}{11}$ minute past 3

D - 32$\frac{5}{11}$ minute past 3

Answer : A

Between Clock

Explanation

It is clear from the figure that minute hand has to travel through 30 minute space.

Therefore 30 minute space can be gained in $\frac{12}{11}$ × 30 = 32 $\frac{8}{11}$ minute past 3

Answer : C

Explanation

$\frac{360}{12} \times \frac{117}{12} = 292\frac{5}{12}$

$\frac{360}{60}$ × 45 = 270

Reflex angle = 360- (292$\frac{5}{12}$ - 270) = 337$\frac{5}{12}$

Q 9 - At which point of time after 5 O` clock, both hands are at right angle to each other for the first time?

A - 5h, 43$\frac{4}{11}$ min

B - 5h, 43$\frac{6}{11}$ min

C - 5h, 43$\frac{5}{11}$ min

D - 5h, 43$\frac{7}{11}$ min

Answer : B

Explanation

(5n + 15) × $\frac{12}{11}$; here n = 5

$= 40 \times \frac{12}{11} = 43\frac{6}{11}$ min past 5

Answer : A

Explanation

(5n ± x) × $\frac{12}{11}$ past n = (5 × 3 ± 4) × $\frac{12}{11}$ = 20 $\frac{8}{11}$ min past 3 and 12 min past 3
