## 1Puzzle 1- Make the triangle face down

Question: There are 10 balls set up in four rows in a manner that they make a triangle. The first row has one ball while the number of balls in the second row is two which increases to three in the third row and the final row has four balls. How will you make the triangle face down if you are allowed to move just three balls?

### Answer:

Well, to make the triangle face down, it’s necessary that the first row has four balls while there remains just one ball in the last row. Since only three balls can be moved, the only ball in the first row should be kept below the last row which has four balls and out of those four balls, two balls need to be moved to the top row (earlier second row) which has two balls. By doing so, the top row will have four balls, the second one will have three balls (as earlier) and the third and fourth rows will have two balls and one ball, respectively.

## 2Puzzle 2- Solve the problem

Question: The image shows a very simple problem of Mathematics in which you just have to subtract; however, it’s not that simple and will require you to use brain. Quite obviously, if we subtract 1 from 102, the result will be 101; however, the answer that we have to ultimately get is 99. How is it possible?

### Answer:

Well, we don’t have the option to change the answer but we can definitely make some changes in the riddle so that we get the desired answer. The square root of 100 is 10 so if we just implement that trick and make it 102 instead of 102, the puzzle that we get will be 100 – 1 and here comes the answer 99.
