The cost of 5 kgs of apples is Rs. 450. The cost of 12 dozen mangoes is Rs. 4320 and the cost of 4 kgs of oranges is Rs. 240. What is the total cost of 8 kg of apples, 8 dozen of mangoes and 8 kg of oranges ?

Solution(By Examveda Team)

Cost of 5 kgs apples Rs. 450
Cost of 1 kg apples Rs. $$\frac{{{\text{450}}}}{5}$$
Cost of 8 kgs apples = $$\frac{{450}}{5} \times 8$$   = Rs.720
Cost of 12 dozens mangoes Rs. 4320
Cost of 1 dozen mangoes Rs. $$\frac{{{\text{4320}}}}{{12}}$$
Cost of 8 dozen mangoes = $$\frac{{4320}}{{12}} \times 8$$   = Rs. 2880
Cost of 4 kgs oranges = Rs. 240
Cost of 1 kg orange = Rs. $$\frac{{{\text{240}}}}{4}$$
Cost of 8 kgs oranges = $$\frac{{240}}{4} \times 8$$   = Rs. 480
Total cost = 720 + 2880 + 480 = Rs. 4080
