Answer 1

hey
______

let the inetgers be x
second be x+30

ratio=x/x+30

a/q to question

x/x+30=2/5
5x=2(x+30)
5x-2x=60
3x=60
x=20

•integers are 20
•x+30=20+30=50

Answer 2

let the first inetger be c

Second integer = c + 30

Ratio = $\frac{c}{c + 30}$

Now :-

$\frac{c}{c + 30}$ = $\frac{2}{5}$

5c = 2 (c + 30)

5c  -2c = 60

3c = 60

c =20

Integers are :-

= 20

=> c + 30 = 20 + 30

=50

Answer = 20 and 50
