Answer : 1. "Rs. 187.50"
Explanation :
For the publisher to earn a profit of 25% S.P = 125% of C.P.
Also Transportation Cost = 10% of C.P.
Let the S.P of 5500 books be Rs. x.
Then, 10 : 125 = 82500 : x ⇒ x = Rs. 
= Rs. 1031250.
⸫ S.P. of one book = Rs. 
= Rs. 187.50.

= 30% of the total expenditure
⸫ Binding Cost and Transportation Cost together have a central angle of 1080.

= Rs. 1968750.
⸫ S.P of one book = Rs. 
= Rs. 157.50
