As far as I can recall there`s a relation, wavelength is inversely proportional to the temperature of the body. This can also be concluded from the equation E=hv, where E=energy which is also proportional to temperature and u know the relation between wavelength and frequency, v. This makes the question very easy. T1/T2= lambda2/lambda1.

You can solve this question by using WEIN’S DISPLACEMENT LAW.It says that the maximum wavelength emitted is inversely propotional to the temperature.T1/T2=lambda2/lambda1.So the ratio will be 350/510
