If 4^99 = D
6^159 = F
3^1752 = A
Then 7^999 is
where ^ represents power of
OPtion
1) H
2) D
3) E
4) F
5) G
6) A
7) B
8) C
9) I
Solution
On solving, 4^99 has 4 in unit’s place and fourth alphabet is D hence code is D.
Similarly on solving, 6^159 has 6 in unit’s place and sixth alphabet is F hence code is F
Take similar steps for finding the code for 7^999.
First set contains three letters B, K, T
Position of B in English alphabet is 2
Position of K in English alphabet is 11=1+1=2
Position of T in English alphabet is 20=2+0=2
Thus all the alphabets of a set have similar positional value.
Similarly for other sets
Now out of ten choices only (I, R) has the same concept
Position of I in English alphabet is 9
Position of R in English alphabet is 18=1+8=9
Coding is as given below:
673 is converted as (6+1)|(7+2)|(3+3), on reversing we get 697,
697 is converted as (6+1)|(9+2)|(7+3), on reversing we get 10117,
10117 is converted as (1+1)|(0+2)|(1+3)|(1+4)|(7+5), on reversing we get 125422

Five set of numbers from 1 to 10 are formed as (1, 2), (3, 4), (5, 6), (7, 8) & (9, 10)
If first set is coded as 5
Second set is coded as 7
Third set is coded as 6
Fourth set is coded as 8
Then code for fifth set is
There are total 5 letters used in the spellings of ONE and TWO. These letters are {O, N, E, T, W} (Repeated letter will not be counted twice)
Similarly for all sets.
First number is 792
Next number is 7*9|9*2= 6318
Next number is 6*3|3*1|1*8= 1838
Similarly for second set
First number is 463
Next number is 4*6|6*3= 2418
Next number is 2*4|4*1|1*8= 848
Take similar steps for obtaining the answer.

Codes are given to the following toothpastes as given below
Toothpaste Code
COLGATE 310861135
CLOSEUP 38101251411
CIBACA 372131
Then code for PEPSODENT is
Alphabets used in the names of following companies are
A B C D E G I L N O P S T U
Numbers are given for the following alphabets in an increasing order
A B C D E G I L N O P S T U
1 2 3 4 5 6 7 8 9 10 11 12 13 14
Codes are formed on the basis of following numbers
For COLGATE code is 3|10|8|6|1|13|5 similarly for others
Middle number of the code represents the number of times a letter comes in the name of subject.
First number of the code is the number of letters used (excluding revised letter) in the name
of subject from first 13 alphabets similarly last number of the code is the number of letters
used (excluding revised letter) in the name of subject from last 13 alphabets.
2 is not equal to 3 â€“ not even for very large values of 2.
