Solution:In a certain code language MAHARAJA is written as ZNUNENWN.
Logic: each letter of the second letter-cluster = each letter of the first letter-cluster +13
Similarly, R + 13 = E, A + 13 = N, I + 13 = V, N + 13 = A, D + 13 = Q, R + 13 = E, O + 13 = B and P + 13 = C.
So, RAINDROP will be coded as in that language: ENVQAEBC.
