Answer:

let first number is X and second is Y.

a/q X/Y=7/5

X=7Y/5--------(1)

A/Q. (X)(Y)= 560-----(2)

out the value of X in equation (2)

7Y/5(Y)= 560

7Y²= 560×5

7Y²=2800

Y²= 400

Y=√400

Y=20

put the value of Y in equation (1)

X=7×20/5

X=7×4

X=28

therefore

first number=X=28

& second number=Y=20
