Question 1190410
<br>
profit on each fries: 1/3 of the selling price of RS 120 = RS 40<br>
profit on each burger: RS 60 more than on fries = RS 40 + RS 60 = RS 100<br>
profit on each sandwich: 125% of the profit on burgers = 1.25(RS 100) = RS 125<br>
profit on 5 fries, 10 burgers, and 15 sandwiches: 5(40)+10(100)+15(125)=200+1000+1875 = 3075<br>
ANSWER: RS 3075<br>
