Question

The rent of the car for 12 hours is fixed and above that and additional amount will be collected for every hour. Sita paid Rs4600 for 17 hours and simran paid rs 3800 for 13 hours calculate the fixed charge and extra charge per hour.

Answer 1

Answer:

Answer:

fixed charge =Rs.3600 and additional charge per hour = Rs.200

Step-by-step explanation:

let x be the fixed charge for 12 hours and y be the additional charge per hour

Sita:

x  +  5y  =   Rs.4600 ..........(1)

Simran:

x  +   1y  =  Rs.3800 ............(2)

subtracting (2)from(1)

x   +   5y    = 4600 _

x   +    y     = 3800

        4y      =800

4y= 800

∴y=800/4=200

y=200.......(3)

substituting (3) in (2)

x+200 = 3800

∴x = 3800 - 200 = 3600

∴x = 3800

y = 200
