First 16 natural numbers are written from bottom to top. The letters of the word ‘BRIGHT' are written in alphabetical order against the multiples of 2 such that one letter is written against one number either from top to bottom or from bottom to top. Only three numbers are left blank and against the rest of the numbers, letters viz. A, C, M, P, Q, Y, and K. A was written against the number 1. P was written against the highest number which is divisible by 5. Only two letters were written between P and C whereas the highest prime number position is blank, and number 7 position is also blank. No numbers were written between R and M. Difference between the number of C and Q was 6. A is two places away from the blank one. Neither K nor Y were written against the highest number and K was not immediate to A.
