Dinari sells fruit and vegetables.
(a) One day the mass of fruit and vegetables he sells is in the ratio
fruit : vegetables = 9 : 8
He sells 48 kg of vegetables.
Find the mass of the fruit he sells.
(b) On another day he receives $280 for the fruit and vegetables he sells.
The $280 is in the ratio
fruit : vegetables = $(c+3) : (c-1)$
Find the amount he receives from selling the fruit.
(c) In one week Dinari buys fruit and vegetables for $1620.
He sells the fruit and vegetables for $1750.
Calculate his percentage profit.
(d) In another week Dinari sells fruit and vegetables for $1738.
He makes a profit of 10%.
Calculate the amount he paid for the fruit and vegetables in that week.
▶️ Answer/Explanation
(a) 54 kg
Using the ratio 9:8, for 8 parts = 48 kg, so 1 part = 6 kg. Therefore, fruit (9 parts) = 9 × 6 = 54 kg.
(b) $142
Total parts = (c+3) + (c-1) = 2c + 2. Setting up the equation: (c+3)/(2c+2) × 280 gives c = 139. Then fruit amount = (139+3)/2 × 280 = $142.
(c) 8.02%
Profit = $1750 – $1620 = $130. Percentage profit = (130/1620) × 100 = 8.02%.
(d) $1580
Let cost price be x. Selling price = 110% of x = 1.1x = $1738. Therefore, x = 1738/1.1 = $1580.
