Step-by-step explanation:
Let a,b be the numbers.
Then according to the problem,
2
a+b
=34 ....... [Arithmetic mean]
or, a+b=68 ........ (1)
And
ab
=16 ........ [Geometric mean]
or, ab=256
or, a(68−a)=256 ........ Using (1)
or, a
2
−68a+256=0
or, (a−64)(a−4)=0
or, a=64,4 then b=4,64.
So the required numbers are 64 and 4.
