Hint: Here we sum up the quantity of milk sold by the booth in the morning and in the evening and multiply it with the price of milk per litre which is unitary method to find the cost of total litres of milk sold in a day.* Unitary method helps us to find the value of multiple objects if we are given the value of one object by just multiplying the value of a single object to the number of objects.Complete step-by-step answer:We have the quantity of milk sold by the booth in the morning as $$130$$ litres And the quantity of milk sold by the booth in the evening as $$70$$ litres So the total quantity of milk sold by the booth in a day will be the sum of quantity of milk sold by booth in the morning and the quantity of milk sold by the booth in the eveningTherefore, total quantity of milk sold by booth in a day is $$130 + 70 = 200$$ litresNow we have cost of milk per litre as $$Rs.52/litre$$Which means one litre of milk is sold at the price $$Rs.52/litre$$Therefore, using a unitary system we can calculate the price at which any quantity of milk is sold by multiplying the cost of one litre of milk to the quantity.We know total quantity of milk sold in a day is $$200$$ litresTherefore, cost of selling $$200$$ litres milk will be $$200 \times Rs.52 = Rs.10,400$$Therefore, total money collected by the booth per day is $$Rs.10,400$$Note: Alternative method:Quantity of milk sold in the morning by the booth is $$130$$ litres  Cost of price per litre is $$Rs.52/litre$$Therefore cost of $$130$$ litres of milk is given by multiplying cost of one litre of milk to quantity of milkSo, cost of $$130$$ litres of milk is $$Rs.52 \times 130 = Rs.6760$$Similarly, Quantity of milk sold in the evening by the booth is $$70$$ litresCost of price per litre is $$Rs.52/litre$$Therefore cost of $$70$$ litres of milk is given by multiplying cost of one litre of milk to quantity of milkSo, cost of $$70$$ litres of milk is $$Rs.52 \times 70 = Rs.3640$$Total money made by the booth is the sum of money made by the booth in the morning and the money made by booth in the eveningTotal money made by the booth is $$Rs.6760 + Rs.3640 = Rs.10,400$$

A milk booth sold \[130\] litres of milk in the morning and \[70\] litres of milk in the evening. If the milk costs \[Rs.52/litre\] how much money does the booth collect per day?
