In a certain coding scheme, 'India is a growing economic power in world' is written as 'ba, fa, ga, si, na, wa, ta, mo'; 'Population of India is growing' is written as 'ja, ka, ba, si, ga'; and 'Culture of India is soft power' is written as 'sa, ka, si, ba, la, wa'. What are the codes for 'power' and 'of'?

'power' is wa and 'of' is ka, obtained by matching common words to common codes.

'power' occurs only in the first and third sentences; their shared codes are ba, si and wa.

'India' and 'is' also lie in both, and the first two sentences fix them as ba and si.

The leftover shared code wa therefore stands for 'power'.

'of' lies in the second and third sentences, whose shared codes beyond ba and si leave ka for 'of'.
