if one and a half women , drink one and a half tea in one and a half minutes . how many tea can 9 women drink in 3 minutes ?
e 18 explanation : more minutes implies more tea . more women implies more tea . the time become twice ( 3 minutes / 1.5 minutes ) . women become six times ( 9 / 1.5 ) . number of tea = 2 * 6 * original ( 1.5 )
divide(multiply(9, 3), divide(const_3, const_2))
