The correct option is A 10−7−20−13−11−24
Given, MACHINE is coded as 19−7−9−14−15−20−11.
Here, every letter is assigned a numerical code obtained by adding 6 to the numeral denoting the position of that letter in the English alphabet.
E.g, A is coded as 1+6=7, M is coded as 13+6=19.
Similarly, the position of letter D, A, N, G, E and R is 4th,1st,14th,7th,5th and 18th respectively in the English alphabet.
So, DANGER is coded as 10−7−20−13−11−24.
Hence, option (A) is the correct answer.
