at a summer camp with 1,500 participants , 1 / 2 of the campers are aged 10 to 12 . next year , the number of campers aged 10 to 12 will increase by 1 / 3 . after this change , what percentage of the total 1,500 campers will the 10 to 12 - year - olds represent ?
"total - 1,500 participants campers are aged 10 to 12 = ( 1 / 2 ) * 1500 = 750 next year , campers are aged 10 to 12 = ( 4 / 3 ) * 750 = 1000 percentage = ( 1000 / 1500 ) * 100 = 66 2 / 3 % answer : option d"
add(multiply(multiply(divide(multiply(divide(add(const_1000, multiply(10, const_100)), 2), add(divide(1, 3), 1)), add(const_1000, multiply(10, const_100))), const_100), 3), divide(multiply(multiply(divide(multiply(divide(add(const_1000, multiply(10, const_100)), 2), add(divide(1, 3), 1)), add(const_1000, multiply(10, const_100))), const_100), 3), const_10))
