A cow needs 2 kg of balanced food per day for her maintenance and 1/2 kg of extra food for each litre of milk she gives. If a cow gives 5/2 litres of milk every day and the prices of 1 kg diet and 1 litre of milk are Rs.7 and Rs.10 respectively, then find out the ratio between the cost of diet she takes and milk she gives.
Dear Student,
Cow gives 2.5 litre of milk, so according to question diet required = 1.25 Kg.
So, Total diet required by cow = 2 Kg + 1.25 Kg = 3.25 Kg
Cost of 1 Kg of diet = Rs.7
Cost of 3.25 Kg of diet =
Cost of 1 Kg of milk = Rs. 10
Cost of 2.5 Kg of milk =
Required ratio =
