Explanation:

We can solve this question in different cases.
Case 1:
Let income of Mahesh = 2k
Income of Kamal = 3k
Expanses of Mahesh = k
Expanses of Kamal = 3k
Saving of Mahesh = 2k – k = k
Saving of Kamal = 4k – 3k = k
i.e. saving of Mahesh = saving of Kamal
case 2:
Let income of Mahesh = 3k
Income of Kamal = 6k
Expanses of Mahesh = k
Expanses of Kamal = 3k
Saving of Mahesh = 3k – k = 2k
Saving of Kamal = 6k – 3k = 3k
i.e. saving of Mahesh is less than saving of Kamal.
Case 3:
Let income of Mahesh = 5k
Income of Kamal = 10k
Expanses of Mahesh = 3k
Expanses of Kamal = 9k
Saving of Mahesh = 5k – 3k = 2k
Saving of Kamal = 10k – 9k = k
i.e. saving of Mahesh is more than saving of Kamal.
Clearly, it is not possible to determine who saves more.
Hence option(4)
