Answer» Let amt for 1st prize=xtherefore, amt for 2nd prize=x-20 amt for 3rdprize=x-20-20=x-40 amt for 4th prize =x-40-20=x-60 therefore,x+(x-20)+(x-40)+(x-60)=280=>4x -120=280=>x=100 therefore, 1st prize=Rs.1002ndprize=Rs.803rdprize=Rs.604thprize=Rs.40 x+(x-20)+(x-40)+(x-60)=280 4x-120=280 or 4x=280+120 or x=400/4 x=100, The value of each prize are 100,80,60,40

9, A sum of 280 is to be used to givefour cash prize. If each prize is Rs 20 less thanin preceding prize. Find the value of each of.the prizes.

Answer»

Let amt for 1st prize=xtherefore, amt for 2nd prize=x-20 amt for 3rdprize=x-20-20=x-40 amt for 4th prize =x-40-20=x-60

therefore,x+(x-20)+(x-40)+(x-60)=280=>4x -120=280=>x=100

therefore,

1st prize=Rs.1002ndprize=Rs.803rdprize=Rs.604thprize=Rs.40

x+(x-20)+(x-40)+(x-60)=280 4x-120=280 or 4x=280+120 or x=400/4 x=100, The value of each prize are 100,80,60,40
