Answer : 1. "Binding Cost and Transportation Cost"
Explanation :
Central angle of 1080 = 
of the total expenditure= 30% of the total expenditure.
From the pie – chart it is clear that:
Binding Cost + Transportation Cost = (20% + 10%) of the total expenditure
= 30% of the total expenditure
⸫ Binding Cost and Transportation Cost together have a central angle of 1080.

Answer : 2. "Rs. 157.50"
Explanation :
Clearly, S.P. of the book = 105% of C.P.
Let the selling price of this edition (of 12500 books) be Rs. x.
Then, 15 : 105 = 281250 : x ⇒ x = Rs. 
= Rs. 1968750.
⸫ S.P of one book = Rs. 
= Rs. 157.50

Answer : 2. "Rs. 37.50"
Explanation :
Clearly, marked price of the book = 120% of C.P
Also, cost of paper = 25% of C.P.

Then, 120 : 25 = 180 : n ⇒ n = Rs. 
= Rs. 37.50
