Temperature where Fahrenheit reading is double Celsius reading: MCQ with Answer and Explanation

Temperature where Fahrenheit reading is double Celsius reading:
A. 160°C
B. 40°C
C. 80°C
D. 320°C
Answer: Option A
Solution (By JKSSB Mock Tests)
F = (9/5)C + 32. Given F = 2C: 2C = 1.8C + 32 ⇒ 0.2C = 32 ⇒ C = 160°. Verify: F = 2×160 = 320°; formula: (9/5)×160+32 = 288+32 = 320°. Memory aid: Solve linear equation for temperature conversion problems. Algebraic manipulation of scale relations frequently tested in competitive exams.
