If the KNIFE is coded as MPKHG, what do the letters DTGCF stand for ?

Solution (By Examveda Team)

First, let's figure out the rule for how KNIFE becomes MPKHG.
We compare each letter from the first word to the second word:
K is changed to M
(If you count in the alphabet: K, L, M. So, K + 2 letters = M)

N is changed to P
(N, O, P. So, N + 2 letters = P)

I is changed to K
(I, J, K. So, I + 2 letters = K)

F is changed to H
(F, G, H. So, F + 2 letters = H)

E is changed to G
(E, F, G. So, E + 2 letters = G)

So, the secret rule (code) is: Each letter is shifted forward by 2 positions in the alphabet.

Now, we need to find what the letters DTGCF stand for. Since DTGCF is the coded word, to find the original word, we need to do the opposite of the coding rule.
If coding was "+2", then decoding will be "-2" (shifting each letter backward by 2 positions).

Let's apply this rule to DTGCF:
D - 2 letters = B (Counting backward: D, C, B)
T - 2 letters = R (Counting backward: T, S, R)
G - 2 letters = E (Counting backward: G, F, E)
C - 2 letters = A (Counting backward: C, B, A)
F - 2 letters = D (Counting backward: F, E, D)

Putting these decoded letters together, we get BREAD.

Therefore, the letters DTGCF stand for BREAD.
Looking at the options, Option B: BREAD is the correct answer.
