. 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.
B: Rs.10, Rs.3
C: Rs.12, Rs.9
D: Rs.14, Rs.5
Construct two variable equations and solve.
Construct two variable equations.
x= fixed charge for the first two days.
y= additional charge for each day.
Now According to question,
and by second condition,
Simplify the above expression and get the result.
Solve equation (1) and (2).
Y=3, and x=10
∴ fixed charge =Rs.10
and the charge for each extra day =Rs.3
So, option (B) is the correct answer.
As a result, the correct option is (b) i.e. Rs.10, Rs.3
