Read Solution (Total 2)
-
- let a and b be the 2 no.s , and a being the smaller
(a+b)*b=204
(b-a)*a=35
on solving
we get
b^2+a^2 = 169=13^2
remembering the pythagorean triplets of 5,12,13.
We get the values of a=5 and b=12 - 10 years agoHelpfull: Yes(2) No(0)
- 12
If larger numkber=x,Smaller number=y
(x+y)x=204,x^2+xy=204 ---(i) &
(x-y)y=35 ,xy-y^2=35 ---(ii)
From (i) & (ii),x^2+y^2=169, So x=12,y=5 - 10 years agoHelpfull: Yes(1) No(1)
