Answer:

single equivalent discount = 14.5 %

Step-by-step explanation:

Let say Price = x

First Discount = 10 %

10% discount = (10/100)x = x/10

Price after discount = x - x/10

= 9x/10

now second 5 % discount is given on 9x/10

5% discount = (5/100) * (9x/10)

= (1/20)*(9x/10)

= 9x/200

Final Price after discount = 9x/10 - 9x/200

= (9x/200)(20 - 1)

= 171x/200

Net Discount = Original Price - Final Price

Net Discount = x - 171x/200

= 29x/200

Net discount % = {(29x/200)/x}* 100

=  29  / 2

= 14.5%

single equivalent discount = 14.5 %
