A manufacturer purchased an item at 30% less than its production cost and sold the item at a price that was \(\frac{1}{7}\) greater than what the manufacturer paid for it. The price at which the manufacturer sold the item was what percent of the item's production cost?
20%
30%
70%
80%
90%
Let the production price be \(p\)
Then, Buying price = \(0.7p\)
And, Selling price = \(\frac{8}{7}(0.7p) = \frac{4p}{5} = 0.8p\)
Clearly, Selling price \(80\)% of the Production price
Hence, option D
You can also assume some numbers;Let the production price be \(100\)
Then, Buying price = \(70\)
And, Selling price = \(\frac{8}{7}(70) = 80\)
Clearly, Selling price \(80\)% of the Production price
