We have to find the production price of the book 

for that take p as the production price

p * 120 %/100 =216

p=2160/12
p=180 INR

so we got the actual price.

Now the 30% increase in production

180 * 30%/100= 54 INR

so the production cost now is 234 INR

234 * 20%/100= 46.4 INR

So the selling price = 280.4 INR
