by (1)
we can get product of smaller no
sqrt(x*y*z)=z
z= 36 then solve xy=36

Soumen Maity  (9 years ago)

both 1 and 2 options are required to ans this question.
for ex, (abc)^1/2=36, So abc= 1296
and a+b+c=17*3=51
so a+b= 51-36=15.............................(i)
ab=1296/36=36............................(ii)

So, a-b= (225-144)^1/2=9

a=12,b=3
so ans is 36

mohit kumar tiwari  (9 years ago)

let assume c is largest num
a^1/2*b^1/2*c^1/2=c
but given that c=36
ab=36
a+b =15
and after solving a=12 and b=3 so ab=36

let x=36
so, (xyz)^1/2 =36
(yz)^1/2 = 6
yz=36

Is this solution Helpfull? Yes | No   

Abhishek nkumar  (9 years ago)

both are required to solve this question.
since yz=36
there is unique values of y & z here. but together by using statement 2 we can find the unique valus of y & z =12,3.
