a boy multiplied 987 by a certain number and obtained 559981 as his answer. if in the answer both 9 are wrong and the other digits are correct, then the correct answer would be:
multiply(subtract(subtract(divide(559981, 987), const_4), const_0_33), 987)
987 = 3 x 7 x 47 so , the required number must be divisible by each one of 3 , 7 , 47 553681 - > ( sum of digits = 28 , not divisible by 3 ) 555181 - > ( sum of digits = 25 , not divisible by 3 ) 555681 is divisible by 3 , 7 , 47 answer c
