ATQ,
Given: List Price = ₹5700 First Discount = 6% Final Selling Price = ₹1875.3 Find: Additional discount % on already discounted price Now, Price after 6% discount 6% of 5700 = 342 Price after 1st discount = 5700 − 342 = ₹5358 Now, Let 2nd discount = x% 5358 × (1 − x/100) = 1875.3 ⇒ (1 − x/100) = 1875.3 / 5358 ≈ 0.35 ⇒ x/100 = 1 − 0.35 = 0.65 ⇒ x = 0.65 × 100 = 65
