Answer:

Given,

The amount paid to the freelancer= 640/-.

To Find,

The contribution of the second marketer in the hire charges.

Solution,

We can simply find this by using ratios and proportions.

The contribution of each marketer in the hire charges must be directly proportional to the time of hiring individually.

This means the second marketer's contribution must be 12x. if the total charge is 36x (11x+ 12x+ 13x).

The total charge = 36x= 640/-.

Second marketer's contribution= 640/36 ×12 /-.

Hence, the second marketer paid a total of Rs. 213.34.
