Answer 2

Answer:

The rate of the second discount is 11.11%.

Step-by-step explanation:

Cost price of watch = Rs.800

Discount % = 10%

Discount = $10\% \times 800 = \frac{10}{100} \times 800 = 80$

So, Discounted price = Rs.800- Rs.80 = Rs.720

Now New CP = Rs.720

SP = Rs.640

Discount %  = $\frac{CP-SP}{CP} \times 100$

Discount %  = $\frac{720-640}{720} \times 100$

Discount %  = $11.11\%$

Hence the rate of the second discount is 11.11%.
