On centigrade scale the temperature of a BUuyincreases by 30 degrees. The increase intemperature on Fahrenheit scale is

Answer»

We know that C = 5/9*(F-32) => F = 9C/5 +32 ....(1)

so, when c is increased to C+30

=> F' = 9(c+30)/5 +32 =9C/5 +9*30/5+32 = 9C/5 +32+ 9*6

=> F' = F+54 ....... ( since 9c/5 +32 = F)

so, in Fahrenheit ,the increase is = 54°F

it's wrong

check it again.. just missed a 9 to be multiplied with 6, while expanding the formula..
