The cost of 10 kg of apples is equal to the cost of 24 kg of rice. The cost of 6 kg of flour equals the cost of 2kg of rice. The cost of each kg of flour is Rs. 20.50. Find the total cost of 4kg of apples, 3kg of rice and 5kg of flour?
Rs.849.40
Rs.877.40
Rs.901.60
Rs.815.20
Explanation:
Given,
Cost of 10kg apples=cost of 24kg rice
Cost of 6kg flour=cost of 2kg rice
Cost of 1kg apples=20.50
Cost of 4kg apples +3kg rice + 5kg flour=?
Solution:
6 kg of flour= 1 kg flour $\times 6$
=20.50 $\times 6$
=Rs.123.
Cost of 6kg flour=cost of 2kg rice
Therefore,2 kg rice =Rs.123.
Then the 24kg of rice =$12 \times 123$ =1476
Cost of 10kg apples=cost of 24kg rice
So,10 kg of apples=Rs.1476
Then the 4kg apples =$\dfrac{1476}{10}$=$147.6 \times 4 $=Rs.590.4
Then, 3 kg of rice=123/2=$61.5 \times 3$=Rs.184.5
Then,5 kg of flour =$20.50 \times 5$=Rs.102.50
Therefore,Total Cost of 4kg apples +3kg rice + 5kg flour
=Rs.590.4+Rs.184.5 +Rs.102.50=Rs.877.40
Given,
Cost of 10kg apples=cost of 24kg rice
Cost of 6kg flour=cost of 2kg rice
Cost of 1kg apples=20.50
Cost of 4kg apples +3kg rice + 5kg flour=?
Solution:
6 kg of flour= 1 kg flour $\times 6$
=20.50 $\times 6$
=Rs.123.
Cost of 6kg flour=cost of 2kg rice
Therefore,2 kg rice =Rs.123.
Then the 24kg of rice =$12 \times 123$ =1476
Cost of 10kg apples=cost of 24kg rice
So,10 kg of apples=Rs.1476
Then the 4kg apples =$\dfrac{1476}{10}$=$147.6 \times 4 $=Rs.590.4
Then, 3 kg of rice=123/2=$61.5 \times 3$=Rs.184.5
Then,5 kg of flour =$20.50 \times 5$=Rs.102.50
Therefore,Total Cost of 4kg apples +3kg rice + 5kg flour
=Rs.590.4+Rs.184.5 +Rs.102.50=Rs.877.40
