Question

In a certain code language, 'DONER' is coded as '52369' and 'DROVE' is coded as '32957'. What is the code for 'N' in the given code language?

• A. 7
• B. 9
• C. 6
• D. 5

Answer 1

Answer:

C. 6

Compare the two coded words carefully:

• DONER → 52369

• DROVE → 32957

Common letter in both words:

• D, O, E

Common digits in both codes:

• 2, 3, 5

Now identify uniquely:

From DONER:

• N and R correspond to remaining digits 6 and 9

From DROVE:

• R, V correspond to remaining digits 9 and 7

Common letter is R, so common digit must be 9.

Therefore:
R = 9

Now in DONER, the remaining unmatched digit is:
N = 6

Final Answer:

The code for N is 6.
