Answer 1

47

Explanation:

SP of jewellery include ₹ 100 making charges = 1000

Where the cost of jewellery = ₹ 900

After 90% discount, 10% of making charges = ₹ 100

Let making charges be = x

`(10"x")/100=100`

x = 1000

Total CP of jewellery = 1000 + 900 = ₹ 1900

Over discount`=(1900-1000)/1900xx100`

`=900/1900xx100`

= 47% approx
