Answer
Answer (as printed): A
Explanation
S.P. in 1st case = 94\% of 70\% of ₹ 700 $$=₹\left(\frac{94}{100} \times \frac{70}{100} \times 700\right)=₹ 460.60 .$$ S.P. in 2nd case = 84\% of 80\% of ₹ 700 $$\begin{aligned} & =₹\left(\frac{84}{100} \times \frac{80}{100} \times 700\right)=₹ 470.40 . \\ & \therefore \quad \text { Difference }=₹(470.40-460.60)=₹ 9.80 . \end{aligned}$$
