Simple trick for clock problem's in Aptitude


Hey guys i am back with another interesting Post.This post is about clock problems which we normally asked in aptitude exams.Aptitude exams play a major role in any interviews.Without clearing Aptitude you cannot even into any interview session.Now lets go back to our clock question. There are many categories in clock problems but major question which is quite time taking and difficult solve in finding the angle between the hands .In clock questions , one of the important question is : 

Q.Find the angle between hour hand and minute hand.

Sol.  So here's a simple trick for it
Suppose the time is X h  : Y min
   The FORMULA for solving the angle between hour and minute hand is the following equation:        
      
Angle between X and Y =|(X*30)-((Y*11)/2)|

Let us take a example solve this problem based on this formula .
Example :
Angle between hands at 5:30 

FORMULA :
Angle between X and Y =|(X*30)-((Y*11)/2)|

Step 1: Here comparing with formula : X=5 , Y=30
Step 2:  Initially we have to multiply hours with mins as shown : 5*30=150
Step 3: Now apply (Y*11)/2) as shown : (30*11)/2 = 165
Step 4:  Now substract answer in step 3 from step 2 as shown :  165-150=15

Thus, angle between hands at 5:30 is 15 degrees.


Last Words:
Clock problems are questions which are always asked in aptitude.Solving some of them are easy but ,solving for angle between clock hand is quite time taking.So ,The formula for solving the Angle between hour and minute hand is                  
(X*30)-((Y*11)/2) |

This trick is only work if (Y*11)/2) is divisible by 2 means after dividing by 2 get you will get remainder zero otherwise it is gives you absurd result. For example check this..find the angel between both the hands when time is 3:05 pm
