a fruit seller had some oranges . he sells 40 % oranges and still has 300 oranges . how many oranges he had originally ?
"explanation : he sells 40 % of oranges and still there are 300 oranges remaining = > 60 % of oranges = 300 ⇒ ( 60 × total oranges ) / 100 = 300 ⇒ total oranges / 100 = 5 ⇒ total oranges = 5 × 100 = 500 answer : option d"
add(300, multiply(300, divide(40, const_100)))
