Two shopkeepers announce the same price of $Rs.700$ for a sewing machine. The first offers successive discounts of $30$ and $6$ while the second offers successive discounts of $20$ and $16$. The shopkeeper that offers better discount, charges ........ less than the other shopkeeper.

• A. $Rs.9.80$
• B. $Rs.16.80$
• C. $Rs.22.40$
• D. $Rs.36.40$

Answer 1

The correct option is A $Rs.9.80$

Price of sewing machine=700
First shopkeeper offers 30% and 6% discount
Then$\frac{30}{100}\times \frac{6}{100}\times 700=12.60$
Second shopker offers 20% and 16% discount
Then$\frac{20}{100}\times \frac{16}{100}\times 700=22.40$
Difference of discount=$22.04-12.06=9.80Rs.$
Hence ,Second shopkeeper offers better discount, charges 9.80 less than the first shopkeeper
