The result of math class test came out.
Fariha’s mark was an even number.
Srabon got a prime!!
Nabila got an odd number.
The sum of the marks of Srabon and Nabila was less than the marks of Fariha.
The pass number was 33.
Total mark was 100.
How many ways were there so that Srabon got passed?

Fariha has a table clock.
After observing the clock whole day, she has come to a conclusion that the angle between the second hand,and the hour hand changes within seconds!!
During 12 hours, the angle can become maximum for many times!
But the angle is always smaller than 180 degree.

NOW!!!!!
Find out the time when the angle becomes maximum!

Shibab wants Nabila’s phone number.
