صرف محمد ثلاث اخماس ما كان بيجيبها ثم ثلاثي الباقي وبقي اربعين درهم حل

Muhammad had 300 dirhams before spending. He spent three-fifths of it, then spent three-fifths of what was left, leaving 40 dirhams. By setting up the equation 40 = 1/3(X – 3/5 X), where X is the initial amount, it was found that X is equal to 300 dirhams. Therefore, Muhammad initially had 300 dirhams, spent a total of 260 dirhams, and was left with 40 dirhams after the second round of spending.
