Concept:This is a data sufficiency question where we check whether each statement alone is enough to find the profit on item B.Explanation:From the question, $\mathrm{SP}_A = \text{Rs. }1840$.Discount on A $= 1840 - 840 = \text{Rs. }1000$.So, $\mathrm{MP}_A = \mathrm{SP}_A + \text{Discount} = 1840 + 1000 = \text{Rs.}2840$.Given $MP_A : MP_B = 3 : 1$, so $MP_B = 2840 \div 3 \approx \text{Rs. }946.67$.Also, $CP_A : CP_B = 4 : 5$.From Statement I:$CP_A = \text{Rs. }700$.Using the ratio, $CP_B = (5/4) \times 700 = \text{Rs. }875$.Profit on B $= 20\%$ of $20\% \text{ of } \text{Rs.}875 = 0.20 \times 875 = \text{Rs.}175$.So, Statement I alone is sufficient.From Statement II:Given $\mathrm{SP}_A - \mathrm{Profit}_B = \text{Rs. }665$.So, $1840 - Profit_B = 665$.Hence, $Profit_B = 1840 - 665 = ₹1175$.So, Statement II alone is sufficient.Answer:Either Statement I or Statement II alone is sufficient to determine the profit on item B.Correct option: C. Either Statement I or Statement II is sufficient.
