Answer 1

s.p of book is rs 70 /-

gain=40%

then find c.p=c.p=100*s.p/(100+40)%

                  =c.p=100*70/140%

                   =c.p=rs 50

so c.p of book is rs 50  

Step-by-step explanation:

Answer 2

c.p of book =RS 70/-

gain =40%

then find c.p

c.p =100×s.p/100+40

c.p=100×70/140

c.p =₹50

then the c.p of the book is ₹50
