Question

In a bag, there are $20kg$ of fruits. If $7\frac{1}{6}kg$ of these fruits be oranges and $8\frac{2}{3}kg$ of these are apples and rest are grapes. Find the mass of the grapes in the bag.

Answer 1

Total mass of fruits in the bag $=20$ kg

Mass of oranges $=7\frac{1}{6}=\frac{43}{6}$ kg

Mass of the apples $8\frac{2}{3}=\frac{26}{3}$ kg

Therefore, Mass of the grapes $=20-\frac{43}{6}-\frac{26}{3}$

$=\frac{120-43-52}{6}$

$=\frac{25}{6}$

$=4\frac{1}{6}$ kg
