a library branch originally contained 18360 volumes , 30 % of which were fiction novels . 1 / 3 of the volumes were transferred to another location and 1 / 2 of the volumes transferred were fiction novels . what percent of the remaining collection was fiction novels ?
"fiction novels = 5,508 transferred to another location = 6,120 transferred fiction novels = 3,060 non transferred fiction novels = 2,448 percent of the remaining collection was fiction novels = 2,448 / ( 18360 - 6120 ) * 100 = > 20 % hence answer will be ( b )"
multiply(divide(multiply(divide(30, const_100), subtract(1, divide(1, 2))), subtract(1, divide(1, 3))), const_100)
