on multiplying a numberz by 153 , the result obtained was 102325 . however , it is found that both the 2 ' s are wrong . find the correct result .
the only thing you actually know about the correct number z is that it is divisible by 153 and has 5 as a factor . you should immediately try to find the factors of 153 and look for them in the options . 153 = 9 * 17 divisibility by 9 is easy to check . only ( d ) satisfies .
multiply(add(subtract(add(multiply(const_100, const_4), multiply(const_100, const_4)), const_100), add(multiply(const_3, const_4), const_3)), 153)
