Question
A vegetable seller had some apples. He sells 50% apples
and still has 650 apples left. Originally, he had _______________ apples.Solution
Let total number of apples he had is 100. Number of apple = 100 × (50/100) = 50 Remaining number of apples he had with him = 100 - 50 = 50 Now, 50 -------- 650 => 1 ------- 13 Therefore, total number of apples originally he had = 13 × 100 = 1300 Â
