Muscle your brain with this beautiful puzzle 😃
P.S. - Required : Pure common sense. Benefit : Development of brain cells.
Pause the video before you Watch the solution. Enjoy Maths (for a change).
I don't know how many of you tried the above puzzle.
It's based on the concept of Square Roots. That LAST TWO DIGITS OF ANY SQUARE ARE BASED ON THE LAST TWO DIGITS OF THE SQUARE OF NUMBERS BETWEEN 0 & 25.
Before re-reading the above sentence consider a few examples.
Square of lets say 39 is 1521, last 2 digits being 21 seen in the square of 11 (which is between 0 & 25).
Square of 57 is 3249, last 2 digits 49 square of 7.
Square of 163 is 26569, last 2 digits 69 square of 13.
Of 194 is 37636, last 2 digits 36 square of 6.
You take any number, square it andthe last 2 digits of the square would be last 2 digits of a number between 0 & 25.
Try it and let me know if it's true. Will tell you a technique of how to find that number (or you can find out and share it here).
God that was some post 😃

CAT is just around the corner.
These videos can be helpful to both beginners as well as pros.
I am posting the link to the Youtube Channel. By the name Sleepy Classes.
I have an exam to write in December, so would be infrequent here.
So here is my warmest and sturdiest of wishes to alllll.
Be calm and rule the exam.
What is the maximum sum you cannot pay using coins of denominations 6 and 7.
You have been given that -
- there is a country where these denominations exist and only these two denominations exist, i.e. there is no other coin/note available in that country except of value 6 or value 7.
- that these coins/notes are available in plenty, i.e. you don't run out of money at all.
-there is no exchange of currencies allowed between two parties, for example if I have to pay someone value 1, I can't do this by giving him coin of value 7 and taking in return coin of value 6.
Example - Assuming I have to pay someone value 1 or 2 or 3 or 4 or 5, I can't do it. Or similarly if I have to pay someone lets say 11, I can't do this as well. Also, lets say if I have to pay value 94 I can do this by giving 10 coins of 7 and 4 coins of 6.
