What is the answer in the blank?




Ans: RI
Explanation: Look at the first row of letters - RA, SC and TE. The 2nd letter of each pair of letters are A, C and E. The pattern is such that it skips by a letter. A to C skips letter B.
C to E skips letter D.
If you look at the 2nd row of letters - QC, RE and SG, the 2nd letter of each pair of letters are C, E and G. Again, it skips a letter to get to the next letter. C to E skips letter D.
E to G skips letter F.
This pattern applies to the last row of letters, PE, QG and ?. From E to G, it skips letter F. So, G to ? will skip letter H. As such,the 2nd letter should I.
If you look at the diagonal row of letters, RA, RE and ?, the first letter R is underlined. This is again a pattern and hence, the first letter of ? should be R.
That makes the answer RI.

Hi 3 Joy

The answer is finally here! Are you excited?

Question:
If there are FIVE people in a room and each shakes hand exactly once with everyone else in the room, how many handshakes will there be?


Okay, I have attached a picture here to help you understand it better. The coloured dots represent people. Each line between the dots represents a handshake. The numbers represent the number of handshakes. Remember the handshake is not supposed to be repeated.

Answer:
10 handshakes


It is best to act it out with 4 other people. It really helps in your understanding.

What is the missing number?

Wow, I am glad you get the right answer. The answer is 18.

How to get it:

Multiply numbers outside the + sign. That means, take 6 x 5. It gives you 30 which can be found between the numbers in the diagram. Try 8 multiplied by 3. It gives you 24. Hence, to get the answer, you need to multiply 6 and 3.
