A fruit seller sold 40% of his apples and was left with 420 apples. What is the number of apples he had initially?
700
Let the number of apples he had initially be x.
Given, (100 - 40)% of x = 420
60% of x = 420
60100×x=420
0.6x = 420
Hence,
x=4200.6 = 42006 = 700
Therefore, the number of apples he had initially = 700
