In a certain code language, “CAUTIOUS” is written as “CUAITUOS”, and “DEADLINE” is written as “DAELDNIE”. How will “ECONOMIC” be written in that language?

EOCONIMC

The logic followed here is;

(the 2nd letter is interchanged with 3rd, 4th with 5th and 6th with 7th)

So,

that's how we get  “CAUTIOUS” is written as “CUAITUOS”.

And,

“DEADLINE” is written as “DAELDNIE”.

Similarly,

“ECONOMIC” be written as EOCONIMC
