Answer:
950×15/100
=142.5
950-142.5=807.5
selling price = 807.5
C.P=100/100+p × S.P
C.P=100/100+20 × 807.5
C.P=672.9
the c.p of the book 672.9

Answer is symbol of money, then 672.91 or 672whole 11/12
Mp= 950
now,
Sp= Mp- Discount
therefore discount= 15/100*950(percentage means anything by 100)
the discount comes as 142.5
Now sp = 950 -142.5=807.5
20% profit was gained
profit means Sp> cp
hence
the cp
= 807.5÷120/100
=807.5*100/120
=8075/12= (symbol of money) 672whole 11/12 or (symbol of money) 672.91
