(i) ${}^{\prime }P+Q^{\prime }$ means 'P is the father of Q'.
(ii) ${}^{\prime }P-Q^{\prime }$ means 'P is the mother of Q'
(iii) ${}^{\prime }P\times Q^{\prime }$ means 'P is the brother of Q'.

Which of the following means 'M is the maternal uncle of T'?

• A. $M÷K-T$
• B. $M\times K-T$
• C. $M\times K+T$
• D. $M÷K+T$
• E. None of these

Answer 1

The correct option is B $M\times K-T$

By applying the decoding method, we can check all the options for the required relationship.
(1) $M÷K-T$ = Rejected

(2) $M\times K-T$ = Selected

Hence, there is no need to check other options.
