Oh you are absolutely right. Q talks about 'factors' ,I misread.

bhai is this the complete qn? i find it difficult to understand "this park?" which park? longest side fine but what is the shape of the park? you have probably taken it from a set of 3 qns and other would add info to it. if we assume it to be a rectangle which i think it must be, answer should be 5600+3shorterside^2 there must be some link that is missing in this qn posted by you about the shorter side. i am sorry if am wrong

the qs. is incomplete.. when he copy pasted it here he forgot add one imp. line.. "A city has a park shaped as a right angled triangle. The Length....... "

Guys,
Ques : 3f(x)+2f(x+59/x-1) = 10x+30.
Find f(7) ?
Solution :
put x=7 in the equation, you will get
3f(7)+2f(11) = 100
put x=11 in the equation, you will get
3f(11)+2f(7) = 140
you will get two equations in f(7) and f(11)
solve the equation you will get f(7).
It's easy one na...
