The correct answer is
6

Finding the Code for 'H'

We are given two coded words and need to find the code for a specific letter.

  • PEST is coded as 4597.
  • HEPS is coded as 7654.

Code Deduction Logic

To find the code for 'H', we compare the letters and numbers in the given codes:

  • Letters in PEST: P, E, S, T
  • Numbers for PEST: 4, 5, 9, 7
  • Letters in HEPS: H, E, P, S
  • Numbers for HEPS: 7, 6, 5, 4

Identifying Letter-Number Mapping

By comparing the two sets:

  • The common letters are E, P, S.
  • The common numbers are 4, 5, 7.
  • This means the letters E, P, and S correspond to the numbers 4, 5, and 7 in some order.
  • The letter T appears only in 'PEST', and the number 9 appears only in the code '4597'. Therefore, T = 9.
  • The letter H appears only in 'HEPS', and the number 6 appears only in the code '7654'. Therefore, H = 6.

Thus, the code for the letter 'H' is 6.
