if the average of 55 , 48 , 507 , 2 , 684 and y is 223 , then what is y ?
y = 42 , because : ( 55 + 48 + 507 + 2 + 684 + y ) / 6 = 223 ( 55 + 48 + 507 + 2 + 684 + y ) / 6 * 6 = 223 * 6 ( 55 + 48 + 507 + 2 + 684 + y ) - 1296 = 1338 - 1296 y = 42 so the correct answer is c , 42 .
subtract(multiply(223, add(const_2, const_4)), add(684, add(2, add(507, add(55, 48)))))
