Question 20
A shopkeeper gives books on rent for reading. She takes a fixed charge for the first two days and an additional charge for each day thereafter. Latika paid Rs. 22 for a book kept for six days, while Anand paid Rs.16 for the book kept for four days. Find the fixed charges and the charge for each extra day.


Solution

Let latika takes a fixed charge for the first two days is Rs. x and additional charge for each day thereafter are Rs. y.
Now, by the first condition
Latika paid Rs. 22 for a book kept for six days i.e.,
                                         x + 4 y = 22
now, subtracting Eq. (ii) from Eq. (i) we get
                                          2y = 6 y = 3
On putting the value of y in Eq. (ii), we get
                                       x + 2 × 3 = 16
                                        x = 16 – 6 = 10
hence,                                  the fixed charge = Rs. 10
and the charge for each extra day = Rs. 3
