Solution

The correct option is B

x+10y=600;x+15y=840


Let x denote the fixed cost and y denote the variable cost/hr.

Here, fixed cost + (variable cost/hr × no. of hours stayed) = Amount paid

For the first person, as he stayed for 10hrs

x+10y=600

For the second person, as he stayed for 15hrs

x+15y=840

Thus, the required equations are x+10y=600 and x+15y=840
