Question

In a certain code, '13' means 'stop smoking' and '59' means 'injurious habit'. What do '9' and '5' mean respectively in that code ?
Statements:
1. '157' means 'stop bad habit'.
2. '839' means 'smoking is injurious'.

• A. I alone is sufficient while II alone is not sufficient
• B. II alone is sufficient while I alone is not sufficient
• C. Either I or II is sufficient
• D. Neither I nor II is sufficient
• E. Both I and II are sufficient

Answer 1

The correct option is C Either I or II is sufficient

'59' means 'injurious habit' and '157' means 'stop bad habit' (from I). Thus, the common code number '5' stands for common word 'habit'. So, '9' represents 'injurious'. Hence, I is sufficient.
Also, '59' means 'injurious habit' and '839' means 'smoking is injurious'. Thus, the common code number '9' stands for common word 'injurious'. So, '5' represents 'habit'. Thus, II is also sufficient.,
