giving a discount of 20%, then the ratio of
cost price to marked price is -
यदि एक पुस्तक विक्रेता की 20% छूट देने के बाद 8% का लाभ
कमाता है, तो क्रय मूल्य का अंकित मूल्य से अनुपात है-
7 (1) 10 : 13 (2) 20 : 26 (3) 20 : 27 (4) 20 : 29​

Answer 1

Answer: 20:27

Step-by-step explanation: Suppose the cost of item is 100 Rs . The shopkeeper earns 8% profit that is 108 rs . So 108 is 80 % because the shopkeeper gives 20% as disc

So ( 108 × 20 / 80 ) = 27 the disc amount

108+27 = 135

Ratio comes to 100:135 that is 20:27
