Quantity of apples purchased = 5 kg
Quanity of apples found rotten = 54 kg
⟹ Quanity of apples that weren't rotten =(5−54) kg = 20−54 kg = 154 kg
Now, 154 kg of apples are to be divided among 4 people.
⟹Each person gets a share of 1544 kg of apples.
But, 1544=154×14=1516.
Thus, the fraction of apples that Darshan got is equal to 1516.
