Problem: a fruit seller had some oranges . he sells 10 % oranges and still has 360 oranges . how many oranges he had originally ?
Rationale: "explanation : he sells 10 % of oranges and still there are 360 oranges remaining = > 90 % of oranges = 360 ⇒ ( 90 × total oranges ) / 100 = 360 ⇒ total oranges / 100 = 4 ⇒ total oranges = 4 × 100 = 400 answer : option d"
annotated_formula: add(360, multiply(360, divide(10, const_100)))
