Management Aptitude Test 2014 Paper

(b) Let, the marked price on item = ₹ 100
Discount allowed = 10% = ₹ 10
∴ Discounted price of item = 100 - 10 = ₹ 90
Sales tax = 8% on ₹ 90 = $\frac{90\times 8}{100}=\frac{72}{10}$ = ₹ 7.20
∴ Total paid amount = 90 + 7.20 = ₹ 97.20
When ₹ 97.20 is paid, then the marked price = ₹ 100
and ₹ 1 is paid, then the marked price = ₹ $\frac{100}{97.20}$
when ₹ 680.40 is paid, then the marked price
= ₹ $\frac{100}{97.20}$ × 680.40
= ₹ $\frac{100\times 6804}{972}$ = ₹ 700
