Question

2. Surbhi has borrowed 3 books from the library. The fine for not returning the books in time is
* 5 per day. She remembers the librarian telling her that the Mathematics book was issued to
her about a week earlier than the 2 Science fiction books. If the total fine paid by Surbhi on
all 3 books is 125, how long was each book overdue?
​

Answer 1

Answer:

no. of days of maths book = 16 days

no. of days of science book = 9 days

Science book = x

Maths book = x+7

5(x+x+7) = 125

5(2x+7) = 125

2x+7 = 25

2x = 18

x= 9
