5 * 2 is a 3 digit number with * is a missing digit . if the number is divisible by 6 , the missing digit is
sol . let the number be 5 x 2 . clearly , it is divisible by 2 . now , 5 + x + 2 = ( 7 + x ) must be divisible by 3 . so , x = 2 . answer b
divide(subtract(add(add(add(multiply(5, const_100), 2), multiply(const_1, const_10)), multiply(const_1, const_10)), add(multiply(5, const_100), 2)), multiply(const_1, const_10))
