17% of 17 + 18% of 18 = 19% of x then x is lying in the range

1) (20, 30)
2) (25, 35)
3) (35, 40)
4) (40, 45)
5) (15, 25)
6) (10, 20)
7) (5, 30)
8) (0, 20)
9) (35, 45)
10)None of these

Answer 1

17*17 + 18*18 = 19*x
x = 613/19 = 32.26

So option 2.

Answer 2

17/100*17+18/100*18=19/100*x
=>(17*117+18*18)/100=19/100*x
=>189+324=19*x
=>x=513/19
=>x=27
Therefore x lies between (20,30)
