In a certain code language, COACH is coded as 90, and POST is coded as 210. How will NOISE be coded in that language?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 186.
The logic used here is:
COACH is coded as 90
COACH = 3 + 15 + 1 + 3 + 8 = 30 × 3 = 90
POST is coded as 210
POST = 16 + 15 + 19 + 20 = 70 × 3 = 210
Similarly,
Code for the word NOISE:
NOISE = 14 + 15 + 9 + 19 + 5 = 62 × 3 = 186
Hence, 186 is the correct answer.
