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 ia the pice of each of these two books ?

Correct Answer: 10,16

Explanation:

Total pice 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) = Rs.(x+(3/5)x) = Rs. (8/5)x


 


So,  x+(8/5)x =26 <=> x =10


 


The prices of the two books are Rs. 10 and Rs. 16
