Correct answer: B

Explanation

The correct answer is option 2 i.e. 520.

Difference of profit % of = (1615−1314)\left(16 \dfrac{1}{5} - 13 \dfrac{1}{4} \right)  = (16.2 - 13.25) = 2.95% (difference of price of Rs. 76.70)

2.95%→76.702.95\% \rightarrow 76.70

100%→(76.702.95×100)100\% \rightarrow \left( \dfrac{76.70}{2.95} \times 100 \right)= Rs. 2600 (which is the CP)

20% of the cost price of the article = 2600 × 20/100 = 520 Rs.
