Answer:375 and 450Explanation:The computation of the initial and the final temperature is shown below:

In condition 1:

The efficiency of a Carnot cycle is

So, the equation is

For condition 2:

Now if the temperature is reduced by 75 degrees So, the efficiency is

Therefore the next equation is

Now solve both the equations

solve equations (1) and (2)

T_2 + 450 = 75

T_2 = 375

Now put the T_2 value in any of the above equation

i.e

T_1 = T_2 + 75T_1 = 375 + 75= 450
