Answer 2

Answer:

The man would be approximately $2.35$ percent worse off.

Explanation:

In the case of the successive increments of the initial case, let us take the salary to be $100$ rupees.

• In the first increment of $20$ percent, his salary would increase to $120$ rupees.
• In the second increment of $30$ percent, his salary would increase to $156$ rupees.
• In the third increment of $25$ percent, his salary would increase to $200$ rupees.

In the case of the second situation, taking the same salary of $100$ rupees.

• In the first increment of $25$ percent, his salary would increase to $125$ rupees.
• In the second increment of $25$ percent, his salary shall increase to $156.25$ rupees.
• In the third increment of $25$ percent, his salary would increase to $195.29$ rupees.

The difference between the two final amounts is $4.7$ rupees, which is $2.35$ percent.
