The cost of 8 kg of cashew nuts is equal to the cost of 50 kg of guavas. The cost of 19 kg of grapes is Rs. 456. The cost of 1 kg of guava is twice the cost of 2 kg of grapes. What is the total cost of 3 kg of cashew nuts and 4 kg of guavas together?

Share

Cost of 19 kgs of Grapes = 456, so cost of 1 kg of Grapes = 24.
Cost of 1 kg of Guava = 2* Cost of 2Kg of grapes = 2 * 2*24 = 96.
Cost of 8 kgs of cashew nuts = Cost of 50 kgs of Guavas i.e. 50*96.
So, cost of 1 kg of cashew nuts = 600.
Total cost of 3 kgs of cashew nuts and 4 kgs of guavas = 3*600 + 4*96 = 1800 + 384 = 2184.
