Question

A sum of 2700 dollar is to be given in the form 63 prizes if the prize is either 100 or 25 dollar find the number of each type

Answer 1

Answer:

Step-by-step explanation:

Let the no of 100 dollar notes be X

And no of 25 dollar notes be Y

So total no of prizes are X+Y----1st eq

Let amount given in 100 dollar notes be 100x

And 25 dollar note be 25 y

Total amount is 2700

So 100X+25Y=2700-------2nd equation

Solve both by elimination method

Since 2nd eq can be written as

4X+Y=108

Solve and get

X=15 Y=48
