Answer & Explanation Answer: C) If the data either in I or II alone are sufficient to answer the question;

Explanation:

'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.

II. Other allowances drawn by Rajan besides his basic salary are Rs 2000 per month which is Rs 50 less than Vasu's salary.

A) II only	B) II and III together
C) I and II together (	D) I, II and III together

Explanation:

From III, we have : Rajan's basic salary = Rs 1550.

From I, we have : Vasu's basic salary = Rs (1550 + 100) = Rs 1650.

From II. we have : Rajan's other allowances = RS 2000

and Vasu's other allowances = Rs 2050.
