Hello.. :)

q 23> See, it says that the fuction takes only rational values and f(1)= 1
=> f(x) = 1
=>f(2) will also be equal to 1.
Therefor, none of the above.

q25> take f(x) = x log x
It satisfies all the conditions given in the que.. and we know it is positive valued as well.
So, option "a"

q30>
take any increasing or decreasing function, you will find tht for some (x,y) , the following inequality does not hold. while for constant function, it does.
So, option "c"
