⚡Hey mate⚡
✨Here is your answer✨
Profit = 12%
Discount = 10%
Let think the dealer sold the book in 900 rupees
It means that 900 rupees is equal to 90% of printed price because he Gave 10 % discount on the book
So 90 % is equal to 900 then 100 % is
90 % = 900
1 % = 900 ÷ 90
1 % = 10
100 % = 10 × 100
100 % = 1000
So the printed price is 1000 rupees
Now we calculate the cost price of the book
So the dealer was earns 12 % profit on the book and we think that the 900 rupees is selling price of the book
It means that 900 rupees is equal to 112 % of the cost price of book
Because 100 % is cost price + 12 % profit on it
Then 112 % is equal to 900 rupees then 100% is??
112 % = 900
1 % = 8.03
100 % = 8.03 × 100
100 % = 803
Now the ratio between cost price and printed price
Cost price : printed price = 803 : 1000
Cost price : printed price = 12 : 45
I hope it's helpful for you. Thank you ❤️
