One-third of a tower is painted black, 511 th of the remaining part is painted red and the rest is painted white. If the white part measures 60 ft.,the total height of the tower is-

Answer: Option C

Let the tower height will be x ft.
∴ Black part will be = $$\frac{1}{3}x$$
Remaining part = $$x-\frac{1}{3}x=\frac{2}{3}x$$
∴ Red part will be = $$\frac{2}{3}x\times \frac{5}{11}=\frac{10}{33}x$$
White part will be = $$\frac{2}{3}x-\frac{10}{33}x=\frac{12x}{33}$$
i.e. $$\frac{12x}{33}$$ = 60
x = 165 ft.
