A watch of marked price Rs. 1200 is sold at successive discounts of 5% and 8%. Find its selling price.

Correct option is A

Given:
Marked Price = 1200
Discounts = 5% then 8%
Formula Used:
$$\text{Successive discount: } SP = MP \times \left(1 - \frac{d_1}{100}\right) \times \left(1 - \frac{d_2}{100}\right)$$​
Solution:

$$\text{After 1st discount, Selling Price} = 1200 \times \frac{95}{100} = 1140\\\ \\\text{After 2nd discount, Selling Price} = 1140 \times \frac{92}{100} = 1048.80$$​​

Selling price = Rs. 1048.80
Alternate Solution:
​$$\text{Net discount} = 5 + 8 - \frac{5 \times 8}{100} = 12.6\%\\\ \\SP = 1200 \times (1 - 0.126) = 1048.8$$​​
