Question

RED is coded as $6720$ then how would GREEN be coded?

• A. $1677199$
• B. $1677209$
• C. $16717209$
• D. $9207716$

Answer 1

The correct option is B $1677209$

Reverse the order of letters and add 2 to the face of each letter and write the number
RED$\to$DER$\to$4518$\to$6720.
Similarly, GREEN$\to$ NEERG$\to$1455187$\to$1677209
Hence, option (B) is the correct answer.
