An article was sold for ₹512 after giving two equal successive discounts on the marked price of ₹800. The percentage discount offered is:
Answer & explanation
Correct answer: option 2
Given=
M.P = 800
S.P = 512
Now, M.P : S.P = 800 : 512 = 400 : 256
Here, two discounts are given successively. So, after one discount the ratio becomes,
M.P : S.P = √400 : √256
M.P : S.P = 20 : 16
Discount% = (20-16) × \(\frac{100}{20}\) = 20%
