- D)
as the solutin is 12109 so 3*3300 gives 9900 and 12109 is greatr than this - 10 years agoHelpfull: Yes(7) No(1)
- Consider a=11,b=25,c=12 and given expression as (a^2)*b+(b^2)*c+(c^2)*a and all options are in terms of a*b*c.
So divide (a^2)*b+(b^2)*c+(c^2)*a by a*b*c.
next you will get (a/c)+(b/a)+(c/b)
Now substitute a,b,c values
then approximately 0.9+2.08+0.4>3
Hence the answer is d.

- Answer will be 3 and as it is not given in the options,hence it will be none.
Take any number divisible of 6 and add 4 and 5 respectively,when u add those and divide by 6 the remainder for all the cases are coming to be 3. - 9 years agoHelpfull: Yes(1) No(0)
