You have two sand timers with you. One can measure 7 minutes and the other sand timer can measure 11 minutes. This means that it takes 7 minutes for the sand timer to completely empty the sand from one portion to the other.

You have to measure 15 minutes using both the timers. How will you measure it ?

There are two numbers with the difference of 3 between them and the difference of their squares is 51. Can you find the numbers?

If you accept the expectations of others, especially negative ones, then you never will change the outcome
