The average price of 10 book 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 0% more then the price of the other, what is the price of each of
these two books ?
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`) = Rs (`x` + `3/5 x)` = Rs.` ((8x)/(5))`
do, `x` +` (8x)/(5)` = 26 `hArr` 13`x` = 130 `hArr` `x` = 10
`:.` The prices of the two books are Rs.10 and Rs. 16.
