Option 3 : Either statement III or statement I and statement II together are sufficient to answer the question.
Considering statement I,
I. Total amount invested in business is Rs. 22,000.
∴ This statement is not sufficient alone
Considering statement II,
II. Profit earned at the end of 3 years is 3/8th of the total investment.

Considering statement III,
III. The average amount of profit earned per year is Rs.2750.
From III, profit after 3 years = (2750 × 3) = Rs. 8250
∴ Praveen’s share = Rs. 8250 × (5/11) = Rs. 3750
∴ This statement is sufficient to answer the question
Considering statements I and II together,
