In a certain code language, 'RUIN' is coded as '3719' and 'RUNG' is coded as '7916'. What is the code for 'G' in the
given code language?

Given: 'RUIN' is coded as '3719' and 'RUNG' is coded as '7916'.

Logic: Direct coding.

R, U and N are common in both while 7, 1 and 9 are common in both.

So, the code of G is 6.

Thus, correct option is (b).
