A cashew nut cultivator cultivates a bumper production of cashew of about 1000kg. The market price for plain cashew nuts is Rs. 200/kg and of roasted cashew nuts is Rs. 1200/kg. What percentage of the crop should be sold as plain cashew nuts to earn 180% profit by year-end, if the production cost of plain cashew nuts is Rs. 100/kg and that of roasted cashew nuts is Rs. 400/kg. Also, find his amount of profit.

Also, find his amount of profit. Correct Answer 20%, Rs. 6,12,000
Solution :
Given data :
Total cultivation of cashew nuts = 1000 kg
The market price of plain cashew nuts = Rs. 200/kg
The market price of roasted cashew nuts = Rs. 1200/kg
Percentage profit in the whole transaction = 180%
The production cost of plain cashew nuts = Rs. 100/kg
The production cost of roasted cashew nuts = Rs. 400/kg
Formulae :
Profit (%) = × 100
Profit = C.P. ×( P%/100)
Calculation :
Percentage profit in plain cashew nuts = × 100
⇒ (100/100) × 100
⇒ 100%
Percentage profit in roasted cashew nuts = × 100
⇒ (800/400) × 100
⇒ 200%
Now applying allegation for-profit percentages of plain cashew nuts and roasted cashew nuts to get overall profit percentage; the resultant ratio got is of quantities of both the varieties of cashew nuts.

Total cashew is 1000 kg
⇒ 1 + 4 = 5 = 1000 kg
⇒ 5 = 1000 kg
Plain cashew,
⇒ 1 = 1000/5 = 200 kg
Rosted cashew,
⇒ 4 = 200 × 4 = 800 kg
⇒ 1/5 of total cashew nuts is to be sold as plain cashew
⇒ Percentage to be sold as plain cashew nuts = (1/5) × 100
⇒ 20%
The production cost of plain cashew nuts = 200 × 100
⇒ Rs. 20,000
The production cost of roasted cashew nuts = 800 × 400
⇒ Rs. 3,20,000
Total production cost = 20,000 + 3,20,000
⇒ Rs. 3,40,000
Total profit = 3,40,000 × (180/100)
⇒ Rs. 6,12,000
∴ The cultivator sells 20% of stocks as plain cashew nuts and earns Rs. 6,12,000 as profit in the whole transaction.
