Answer:
Step-by-step explanationLet initial amount be 100
1> First discount is 70% then remaining price is 30
2>Second discount is 30% of remaining that is
30% of 30 which is 9
thus remaining is 30–9=21
Hence on 100 rs two successive discount of 70 and 30 lead to a price of 21
so total discount received = 100–21=79
Hence equivalent discount % = (79/100)*100=79%
