For e.g. A+Z=1+26=27               C+X=3+24=27 *To remember the alphabets and its reverse, form a story like this AhraZ   is a BoY who is CompleX by nature and he loves to DraW pictures of EnVironment in his FaltU time. he GoT a painting from HarSh,(his friend) which was IrregulaR in shape and has a picture of Jacket-Quilt. Harsh wanted him to KeeP the painting. He also gifted him shoes of LottO and he looked like gentleMaN after wearing it.                                                                                                                                                                                                                                                Numeric Types: i)Based on the position of the alphabet. e.g.   If FLOW is coded as 6121523, then BAT=2120 ii)Based on reverse position of alphabet. e.g If Flow is coded as 2115124, then BAT=25267 iii)Based on the Sum of the position of alphabets. e.g.If Flow is 56,BAT=23                                                                                                                                          Symbols Some special characters will be representing the alphabets or numbers. Trick: I)identify the repeating letters and symbols in a word. II)Identify the repeating letters in different words. Remember, The letter sequence and symbol sequence need not be the same. e.g.if FOOD is written as '$*@*',DOOR =? Here,* is repeating so, O=*, D=$/@. Here comes the need for options. Go to Option and check if anyone Contains a strange symbol,$/@ and * Good Luck!
