(#M40000579) TCS QUESTION Keep an EYE

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 hour has 90 min while each minute has 60 sec. As on earth, the hour hand covers the dial twice every day. Find the approximate angle between the hands of a clock on Oz when the time is 12:40 am.
a) 71
b) 251
c) 111
d) 89

Solution

Since total hours in a day = 36 and
as on earth, the hour hand covers the dial twice every day.
so there will be 18 numbers from 1 to 18 in the clock.
when the time will be 12:40(hands will be at 12 and 8 marks in the clock), two hands of the clock will make an angle of 20*4 = 80 degree, here 20 is the angle between two numbers in the clock.
now for 80 min, advancement of the hour hand will be (20/90)*40 = 80/9
so total angle = 80 + (80/9) = 800/9 = 88.889 degree
if we consider the obtuse angle, then it will be 360-88.889 = 271.111 degree
