ClocK and ur ans

If you look at a clock and the time is 3:15.
What is the angle between the hour and the minute hands? ( The answer to this is not zero!)




Answer
7.5 degrees
At 3:15 minute hand will be perfactly horizontal pointing towards 3. Whereas hour hand will
be towards 4. Also, hour hand must have covered 1/4 of angle between 3 and 4.
The angle between two adjacent digits is 360/12 = 30 degrees.
Hence 1/4 of it is 7.5 degrees.

A safe number

There is a safe with a 5 digit number as the key. The 4th digit is 4 greater than the
second digit, while the 3rd digit is 3 less than the 2nd digit. The 1st digit is thrice the
last digit. There are 3 pairs whose sum is 11.
Find the number.
