(b)Second offer
(c)Third offer

Answer
Answer (as printed): C
Explanation
Let the M.P. of an article be ₹ 100. We may calculate the final price of this article under each of the three offers: (i) Final price = 85\% of 75\% of ₹ 100 $$=₹\left(\frac{85}{100} \times \frac{75}{100} \times 100\right)=₹ 63.75$$ (ii) Final price = 90\% of 70\% of ₹ 100 $$=₹\left(\frac{90}{100} \times \frac{70}{100} \times 100\right)=₹ 63$$ (iii) Final price = 95\% of 65\% of ₹ 100 $$=₹\left(\frac{95}{100} \times \frac{65}{100} \times 100\right)=₹ 61.75 .$$ The final price is lowest in (iii). So, it is the best offer.
