On the planet Oz, there are 8 days in a week- sunday to saturday and another day called Oz day.There are 36 hours in a day and each hours has 90 minutes while each minute has 60 seconds.As on the earth, the hour hand covers the dial twice everyday. Find the approximate angle between the hands of a clock on Oz when the time is 12:40am.	Select the correct option
A) > 111 degrees
B) > 251 degrees
C) > 71 degrees
D) > 89 degrees
E) > 99 degrees
As, we have 36 hour in a day. So, the dial has 18 hours(36/2=18) to cover daily twice. Now a dial has 360*. So, in one hour hand moves 360/18=

<output>20</output>
20*.   So, for 12 hour hand moves 12x20=240*.   Now for minutes, hour hand moves 20/90   for 40 minutes it moves 20/90x40=8.88*   So for 12:40 hour hand moves   240+8.88= 
<gadget id="calculator">  240+8.88</gadget>
<output>248.88</output>
248.88*.   Now, minute hand moves 90 minutes to complete one hour.   for one minute it moves 360/90= 
<gadget id="calculator">360/90</gadget>
<output>4</output>
4*   for 40 minutes it moves 4x40=160*   So, the angle between hour hand and minute hand is 248.88-160= 
<gadget id="calculator">248.88-160</gadget>
<output>88.88</output>
88.88   The ans is 89*   ANSWER:&gt; 89 degrees
