Which of the following temperature will read the same value on celsius and Fahrenheit scales?
पर्याय
- 40°
+ 40°
- 80°
- 20°
उत्तर
- 40°
Explanation:
`(("F" - 32)/180)100 = "C"`
Temperature (F, C) `→` T
`("T" - 32)/180 = "T"/100`
T − 32 = `(9"T")/5`
`"T" - (9"T")/5` = 32
`(5"T" - 9"T")/5` = 32
`(-"4T")/5` = 32
T = `(32 xx 5)/-4`
T = - 40°
