Q 4 - At what time between 8 and 9 O`clock in the morning, will the hands of a clock be at right angle?
A - $\frac{574}{11}$ min past 8, $\frac{384}{11}$ min past 8
B - $\frac{575}{11}$ min past 8, $\frac{377}{11}$ min past 8
C - $\frac{576}{11}$ min past 8, $\frac{376}{11}$ min past 8
D - $\frac{577}{11}$ min past 8, $\frac{374}{11}$ min past 8
Answer : A
Explanation
(5n±8) × $\frac{12}{11}$; n = 8
$\frac{574}{11}$ min. past 8, $\frac{384}{11}$ min past 8
Q 5 - A watch which gains uniformly is 2 minutes slow at noon on Monday and 4 min 48 sec fast at 2.40 pm on the following day. At what time it was correct?
Answer : B
Explanation
From 12 noon to 2 pm on the following day
There are 7 day and 2 hours = 170 hours
Now watch gains 2 + 4$\frac{4}{5}$ = $\frac{34}{5}$ min in 170 hrs
It will gain 2 min $\frac{170 \times 5}{34}$ × 12 = 50 hrs = 2 days 2 hrs.
Q 6 - At which time the hands of a clock in between 11 and 12 O`clock will 6 min space apart?
A - 65$\frac{6}{11}$ min past 11 and 52$\frac{5}{11}$ min past 11
B - 64$\frac{6}{11}$ min past 11 and 52$\frac{5}{11}$ min past 11
C - 63$\frac{6}{11}$ min past 11 and 50$\frac{5}{11}$ min past 11
D - 66$\frac{6}{11}$ min past 11 and 53$\frac{5}{11}$ min past 11
Answer : D
Explanation
(5n ± x) × $\frac{12}{11}$ min past `n; here n = 11
(5 × 11 ± 6) × $\frac{12}{11}$ = 66$\frac{6}{11}$ min past 11 and 53$\frac{5}{11}$ min past 11
Q 7 - At what time between 7 and 8 O`clock will the hands of a clock be in opposite direction?
A - 20$\frac{10}{11}$ minute past 7
B - 30$\frac{10}{11}$ minute past 7
Answer : C
Explanation
From the figure it is clear that the minute hand has to gain 10 minute space in order to be in opposite of hour hand, therefore 10 minute space can be gained in $\frac{60}{55}$ × 10 = 10$\frac{10}{11}$
Q 8 - At what time from 10 O `clock to 11 O` clock the hands coincide each other?
Answer : D
Explanation
$\frac{60}{55}$ × 53 = 57$\frac{6}{11}$

Explanation
Required angle = 240 170 = 70o
Q 10 - At what time between 3 O`clock and 4 O`clock will the hands of a clock be in opposite direction?
A - 49$\frac{1}{11}$ min past 3
B - 50$\frac{1}{11}$ min past 3
Answer : A
Explanation
$\frac{\left ( 5n + 30 \right ) \times 12}{11}$ (n>6) min past n
So 49$\frac{1}{11}$ min past 3 is correct.
