Given : Wholesaler bought cashews at four time price than peanuts for per kg. Wholesaler sold 10 kg peanuts at 105 profit and 15 kg cashews at 20% profit to shopkeeper.
Shopkeeper lost 3 kg peanuts and 4 kg cashews in transit.
Shopkeeper then mixed remaining and sold at rs 166 per kg and made 20 % profit
To find : Price of cashew per kg at which wholesaler bought .
Solution:
Let say wholesaler bought cashew for = 4x rs per kg
and peanuts for = x rs per kg
10 kg peanuts sold at 10 % profits = 10x + (10/100)10x = 11x rs
15 kg cashews sold at 20 % profits = 15(4x) + (20/100) 15(4x) = 72x rs
Cost price for shopkeeper = 11x + 72x = 83x Rs
20% profit = (20/100)83x = 16.6x rs
Selling Price = 83x + 16.6x = 99.6x Rs
Total Qty = 10 + 15 = 25 kg
Lost in transit = 3 + 4 = 7 kg
Quantity available for sell = 25 - 7 = 18 kg
price per kg = 166 rs
Selling Price = 166 * 18 Rs
Equate selling price
99.6x = 166 * 18
=> x = 30
4x = 120
Hence wholesaler bought cashew for = 120 rs per kg
