A Carnot engine, whose efficiency is 20% receives heat at 450 K. If it...
Explanation:

Given:
Efficiency of the Carnot engine, η1 = 20%
Temperature of heat intake, T1 = 450 K
New efficiency, η2 = 30%

Formula:
Efficiency of Carnot engine, η = 1 - (T2 / T1)
where T2 is the exhaust temperature

Calculation:
For initial efficiency:
η1 = 1 - (T2 / 450)
0.2 = 1 - (T2 / 450)
T2 = 0.8 * 450
T2 = 360 K
For increased efficiency:
η2 = 1 - (T2 / T1)
0.3 = 1 - (T2 / T1)
0.7 = T2 / T1
T1 = T2 / 0.7
T1 = 360 / 0.7
T1 ≈ 514 K
Therefore, the intake temperature for the same exhaust temperature is approximately 514 K, which is option 'A'.
