Answer – A (Rs 10 and Rs 16) Explanation – Total price of the two books = Rs. [(12 x 10) – (11.75 x 8)] = Rs. (120 – 94) = Rs. 26 Let the price of one book be Rs.x Then, the price of other book = Rs. (x + 60% of x )= x + (3/5)x= (8/5)x so, x +(8/5)x=26 , x=10 The prices of the two books are Rs. 10 and Rs. 16

Given data:
- Average price of 10 books = Rs. 12
- Average price of 8 books = Rs. 11.75
Let's solve the problem step by step:
1. Finding the total cost of 10 books:
- Total cost of 10 books = Average price * Number of books = Rs. 12 * 10 = Rs. 120
2. Finding the total cost of 8 books:
- Total cost of 8 books = Average price * Number of books = Rs. 11.75 * 8 = Rs. 94
3. Calculating the total cost of the remaining 2 books:
- Cost of the remaining 2 books = Total cost of 10 books - Total cost of 8 books = Rs. 120 - Rs. 94 = Rs. 26
4. Setting up equations for the prices of the remaining 2 books:
- Let the price of one book be x
- Price of the other book = 1.6x (60% more than the first book)
5. Equation 1:
- x + 1.6x = 26 (Sum of the prices of the two books equals Rs. 26)
6. Solving Equation 1:
- 2.6x = 26
- x = 26 / 2.6
- x = Rs. 10
7. Calculating the price of the other book:
- Price of the other book = 1.6 * 10 = Rs. 16
Therefore, the prices of the two books are:
- Rs. 10 and Rs. 16
So, option A (Rs. 10 and Rs. 16) is the correct answer.
- Average price of 10 books = Rs. 12
- Average price of 8 books = Rs. 11.75
Let's solve the problem step by step:
1. Finding the total cost of 10 books:
- Total cost of 10 books = Average price * Number of books = Rs. 12 * 10 = Rs. 120
2. Finding the total cost of 8 books:
- Total cost of 8 books = Average price * Number of books = Rs. 11.75 * 8 = Rs. 94
3. Calculating the total cost of the remaining 2 books:
- Cost of the remaining 2 books = Total cost of 10 books - Total cost of 8 books = Rs. 120 - Rs. 94 = Rs. 26
4. Setting up equations for the prices of the remaining 2 books:
- Let the price of one book be x
- Price of the other book = 1.6x (60% more than the first book)
5. Equation 1:
- x + 1.6x = 26 (Sum of the prices of the two books equals Rs. 26)
6. Solving Equation 1:
- 2.6x = 26
- x = 26 / 2.6
- x = Rs. 10
7. Calculating the price of the other book:
- Price of the other book = 1.6 * 10 = Rs. 16
Therefore, the prices of the two books are:
- Rs. 10 and Rs. 16
So, option A (Rs. 10 and Rs. 16) is the correct answer.
