Question

How many pairs of letters (both forward and backward direction) are there in the word ``STRENGTHEN'' each of which have as many letters between them in the word as they have between them in the English alphabetical series?

• A. 1
• B. 2
• C. 3
• D. 4
• E. 5

Hint:

To solve this faster, write the numerical position of each letter above it:
S(19) T(20) R(18) E(5) N(14) G(7) T(20) H(8) E(5) N(14)
Then, for each number, check if $Position + n = Value$. For example, for E(5) at position 4, the 6th position is G(7). $5 + (6-4) = 7$. Match!

Answer 1
