Answer 2

Answer:

The numbers are 500 and 400

Step-by-step explanation:

let the two numbers be x and y ; such that x is a bigger number and y is smaller number..

x+y=900 ------> eq 1

20% of x = 25% of y

20x = 25y

20x - 25y = 0

Divide the equation by 5

4x -5y = 0 --------> eq2

Multiply eq 1 with 4

we get, 4x +4y = 3600 -------->eq3

solve eq 2& eq3

4x -5y = 0

4x+4y = 3600

- - -

-9y = -3600

y = 400

put y=400 in eq 1

x +400=900

x=500
