A fruit vendor disposed of 70% of his stock of apples. If, after this transaction, he is left with 720 apples, determine the initial quantity of apples he possessed.

Correct option is D

Given:
Percentage of apples disposed = 70%
Number of apples remaining = 720
Formula Used:
Total = $$\frac{Remaining\ part}{Remaining\ percentage}$$​ × 100
Solution:
Let the initial quantity of apples be 100%.
Calculate the percentage of apples remaining:
100 - 70 = 30
This 30% of the initial stock corresponds to the 720 apples left.
Let the total initial quantity be T.
T × $$\frac{30}{100}$$​ = 720
T = $$\frac{720 × 100}{30}$$​​
T = 24 × 100 = 2400
The initial quantity of apples was 2400.
Final Answer
So the correct answer is (d)
