Question

The total price of 10 books is Rs. 120 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 40% more than the price of the other, the price difference between these two books is nearly:

• A. 3.34
• B. 4.34
• C. 4.86
• D. 3.86
• E. 4.75

Answer 1

The correct option is B

4.34

Total price of the two books = 120 - (11.75 x 8) = Rs. 26.

Let the price of one of the books be Rs.x.

Then, price of the other book is 1.4x.

2.4x = 26

$⟹$ x = 10.83

Price of one book = Rs. 10.83

$\therefore$ Price of the other book = 1.4x = 15.17.

$\therefore$ Price difference of these books = Rs.4.34.
