Answer:
= Let prize valued ruppess 500 be x
= Then prize valued ruppess 100 be ( 200 x )
= A/Q
= 500 × x + 100 × ( 200 - x ) = 80000
= 500x + 20000 - 100x = 80000
= 400x = 80000 - 20000
= 400x = 60000
= x = 60000/400
= x = 150
= Then prize valued ruppess 500 = 150
= The prize valued ruppess 100 = ( 200 - x )
= 200 - 50 = 150
= ruppess 500 × 150 = ruppess 75000
= ruppess 100 × 50 = ruppess + 5000
ruppess 80000
