Question
In a certain code language, ‘PLATFORM’ is coded as
‘RJDQJKWI’, then ‘FLAMINGO’ is coded as ____ in the same code language.Solution
The logic followed here is: The 1st, 3rd, 5th and 7th letters are replaced by their 2nd, 3rd, 4th and 5th succeeding letters respectively and the 2nd, 4th, 6th and 8th letters are replaced by their 2nd, 3rd, 4th and 5th preceding letters respectively. P + 2 = R L – 2 = J A + 3 = D T – 3 = Q F + 4 = J O – 4 = K R + 5 = W M – 5 = I Similarly, F + 2 = H L – 2 = J A + 3 = D M – 3 = J I + 4 = M N – 4 = J G + 5 = L O – 5 = J
