Answer 1

Let the two natural numbers be x and y
X+y=8
X=8-y ......(i)
1/x+1/y=8/15 ........(ii)
So,
1/8-y+1/y=8/15
Y+8-y/-y2+8y=8/15
8/-y2+8y=8/15
120=-8y2+64y
-8y2+64y=120
-8y2+64y-120=0
8y2-64y+120=0
y2-8y+15=0
y2-5y-3y+15=0
sum=-8
Product=15
y(y-5)-3(y-5)=0
y-5=0 y-3=0
y=5 or y=3
If y=5 then x=8-5
X=3
If y=3 then x=8-3
X=5..
hence nos. are 3 n 5...

hope this will help
