Question

Hassan sells fruit and vegetables at the market.
(a) The mass of fruit and vegetables he sells is in the ratio fruit : vegetables
= 5 : 7. Hassan sells 1.33 tonnes of vegetables. How many kilograms of fruit does he sell?

Answer 1

Answer: 950 kg

Step-by-step explanation:

Given

Hassan sells a total of $1.33\ \text{tonnes}$ of vegetables

The ratio of the mass of fruit to the vegetables is $5:7$

Suppose $x\ \text{tonnes}$ is the total mass of stuff

For vegetables, we can write

$\Rightarrow x\times \dfrac{7}{5+7}=1.33\\\\\Rightarrow x=1.33\times \dfrac{12}{7}=2.28\ \text{tonnes}$

For fruits

$\Rightarrow 2.28\times \dfrac{5}{5+7}=0.95\ \text{tonnes}\approx 950\ kg$
