#### Some alphabets are absent from the alphabet series, but they are provided as replacements below it in that sequence. Select the appropriate option. J10R, M20P, P43N, S90L, G4T

Correct! Wrong!

Explanation
The first letter of each term is moved three steps forward and the last letter is moved two steps backward to obtain the corresponding letters of the next term.

#### Twelve participants in a conference shook hands before and after the meeting. How many handshakes took place in total?

Correct! Wrong!

Then add 9 for the third person, and 8 for the fourth one & proceeding in this fashion we get: 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 66. Hence 66 handshakes took place before & 66 after the meeting, for a total of 132
