Problem: the present population of a town is 60,000 . the population increases annually at 10 % . find the population after 3 years .
Rationale: "explanation : solution : the required population is 60000 ( 1 + 10 / 100 ) ^ 3 = 60000 * 110 / 100 * 110 / 100 * 110 / 100 = 79,860 answer : b"
annotated_formula: add(60,000, divide(multiply(60,000, 10), const_100))
