(a)₹ 850
(b)₹ 890
(c)₹ 930
(d)₹ 950
Answer
Answer (as printed): B
Explanation
110\% of 90\% of 120\% of $\mathrm{A}=1188$ $$\Rightarrow \frac{110}{100} \times \frac{90}{100} \times \frac{120}{100} \mathrm{A}=1188 \Rightarrow \frac{1188}{1000} \mathrm{A}=1188 \Rightarrow \mathrm{A}=1000 .$$ ∴ A purchased it for ₹ $(1000-110)=₹ 890$.
