Solution:
Total Discount = 1000 - 630 = ₹370
Percent Total Discount = (370/1000)*100 = 37%

Since, also Total Discount = x+y - xy/100
Here, x= First Discount
& y= Second Discount

On substituting the values we have,
37 = 30 + y - (30*y)/100
37 = 30 + 0.70y
Therefore, y = 10%

Hence the Second Discount is 10%
