 \frac{12x}{100} - \frac{(100 - x)8}{100} = \frac{11x}{100} \\ 12x + 8x = 1900 \\x = 95
95 books at a rate of profit of 12%
if you have doubt comment below

aRKe09: x+{(x*108*(100/3))/100)}= (16850-x)+[((16850-x)* 104*(100/3))/100)]
aRKe09: in question it gives amount will be equal
pradeep91kc: yes
