Question
The average price of 10 books is Rs. 12 while the average price of 8 of these books is Rs. 11.75. Of the remaining two books, if the price of one book is 60% more than the price of the other, what is the price of each of these two books?
Answer: Option A
- 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 = Rs. 8x 5
So, x + 8x 5 = 26
