A basket 2

A basket contains three types of fruits weighing 87/4 kg in all. If 23/4 kilograms of these are oranges, 48/7 kg are mangoes, and the rest are apples. What is the weight of the apples in the basket?

Correct answer:

a =  9.1429 kg

Step-by-step explanation:

$$\begin{gathered} b={\displaystyle \frac{87}{4}}=21.75\text{ kg } \\ o={\displaystyle \frac{23}{4}}=5.75\text{ kg } \\ m={\displaystyle \frac{48}{7}}\doteq 6.8571\text{ kg } \\ f=m+o=6.8571+5.75={\displaystyle \frac{353}{28}}\doteq 12.6071\text{ kg } \\ a=b-f=21.75-12.6071={\displaystyle \frac{64}{7}}\text{ kg}=9.1429\text{ kg} \end{gathered}$$
