Answer:
Let the fixed charge for first three days and each day charge thereafter be:
According to the question:
x + 4y = 27 ... (i)
x + 2y = 21 ... (ii)
Subtracting equation (ii) from equation (i),
We get:
2y = 6
y = 3 ... (iii)
Putting in equation (i),
We get:
x + 12 = 27
x = 27 - 12
x = 15
Hence:
Fixed charge = Rs. 15
Charge per day = Rs. 3
