82 a 7 + 6 b ____ 190 if a and b represent positive single digits in the correctly worked computation above , what is the value of a + 2 b ?
adding the digits in unit ' s place , 2 + 7 + b = 10 ( since a and b are positive single digits ) = > b = 1 now adding the digits in ten ' s place , 8 + a + 6 + 1 = 19 ( 1 has been carried over from unit ' s place addition ) = > a = 4 a + 2 b = 4 + 2 * 1 = 6 answer b
add(multiply(subtract(subtract(subtract(subtract(190, multiply(6, const_10)), 82), 7), multiply(floor(divide(subtract(subtract(subtract(190, multiply(6, const_10)), 82), 7), const_10)), const_10)), 2), floor(divide(subtract(subtract(subtract(190, multiply(6, const_10)), 82), 7), const_10)))
