B) Rs. 8, Rs. 12
C) Rs. 16, Rs. 10
D) Rs. 12, Rs. 14
E) NOne
Solution:   Total cost of 10 books = Rs. 120   Total cost of 8 books = Rs. 94   =&gt; The cost of 2 books = Rs. 26   Let the price of each book be x and y.   =&gt; x + y = 26 ---------------- (1)   (160/100)y+y =26   On Solving for y, we get   y = 10.   Now, Substituting y = 10 in (1) we get,   x + 10 = 26   x = 16.   So the price of each book is Rs. 16 and Rs. 10 respectively.   Answer: Option Rs. 16, Rs. 10
