Given Information:
Ankita had 4kg cashews, 14kg peanuts, and 6kg almonds.
She planned to make a total profit of ₹1752 by selling these nuts.
2. Average Buying Price:
Let's assume the average buying price of these nuts is "x" rupees per kg.
3. Marked Price and Selling:
Ankita planned to make a profit of ₹73 on these 24kgs of nuts.
So, the marked price of these 24kgs of nuts is ₹(x+73) per kg.
4. Selling Calculation:
She sells 4 kg of the mixture at the marked price of ₹(x+73) per kg.
She sells the remaining 20kg at a 20% discount on the marked price, which is 0.8 times the marked price.
Total selling price = \(4(x+73)+0.8\times20(x + 73)\)
5. Profit Calculation:
Total Profit = Selling Price - Cost Price
₹1752=\([4(x+73)+0.8\times20(x+73)]\)- Cost Price
6. Calculating Cost Price:
Solve the above equation for Cost Price:
₹1752=4x+292+16x+1160-Cost Price
Cost Price=4x+292+16x+1160-₹1752
Cost Price=20x-300
7.Using Given Information about Costs:
We are given that the cost of 7kg cashews is the same as the cost of 30kg peanuts or 9kg almonds:
7C=30P=9A
8. Solving for Costs:
Let 7C=30P=9A=630k (k is a constant)
C=90k, P=21k, A=70k
9. Calculating Total Cost:
The buying price of 4kg cashews, 14kg peanuts, and 6kg almonds is:
Total Cost=4C+14P+6A
Total Cost=4(90k)+14(21k)+6(70k)
Total Cost=360k+294k+420k=1074k
10. Calculating k:
We know that the total cost is ₹4296:
1074k=4296
k=4
11. Calculating Amount Spent on Almonds:
The cost of almonds is A=70k=280
Amount Spent on Almonds=6A=\(6\times280\) = ₹1680
So, the amount Ankita had spent on buying almonds is ₹1680.
Given :
Ankita bought 4C, 14P and 6A
7C = 30P = 9A
Let's assume that 7C = 30P = 9A = 630k
Now , C = 90k, P = 21k, and A = 70k
Cost price of 4C, 14P and 6A :
4(90k) + 14(21k) + 6(70k) = 1074k
Marked up price is 1074k + 1752
Selling price = \(\frac{1}{6}(1074k+1752)+(\frac{4}{5})(\frac{5}{6})(1074k+1752)\)
\(=\frac{5}{6}(1074k+1752)\)
Profit = Selling Price - Cost Price
\(1460-\frac{1074k}{6}=744\)
\(\frac{1074k}{6}=716\)
Therefore, k = 4
Now , money spent on buying almonds :
420k = 420 × 4
= 1680rs
Therefore, the correct option is (A) : 1680
