According to principle of superposition...
y = y+ y2
​So...y = 0.4 [ sin(500pieT) + sin(508pieT) ]
Use sinc + sind formula..
 Sinc + sind = 2sin[(c+d)/2].cos[(c-d)/2]...
Then u will get... Y = 0.8[sin(504pieT).(cos4pieT)]
Here, ₩ (omega) = 504pieT 
We know that...₩ = 2pie×(n)
So...    504pie = 2pie × n
so...n = 252 hz... I think the answer is  3rd option...
