Answer 2

Answer&Explanation:

Let the amount of first prize be Rs 'a'

According to the question,

The amount of first prize=a-200

The amount of second prize=a-2×200=a-400

The amount of third prize=a-3×200=a-600

a+a-200+a-400+a-600=2800

4a-1200=2800

4a=2800+1200

4a=4000

a=4000/4

a=1000

First prize=1000Rs

Second prize=a-200=1000-200=800Rs

Third prize=a-400=1000-400=600Rs

Fourth prize=a-600=1000-600=400Rs
