Question

A sum of Rs 3125 is to be given in the form of
75 prizes. If a prize is either rs 25 or rs 50.
find the number of prizes of each type.​

Answer 1

Answer:

25

Step-by-step explanation:

Let the number of prizes of money 25 be x, and the number of prizes of cost 50 be y ;

x+y = 75

y = 75-x ---------eq 1

25x+50y= 3125

25x + 50(75-x) =3125

25x + 3750-50x = 3125

3750-25x = 3125

625 = 25x

x = 25 -----------eq 2

putting value of x in eq 1, we get,

y = 75-25

  = 50

Hence the number of prizes of each type are 25 while other type of prizes are 50.
