If on a hot summer day, the difference between the temperature in CELSIUS and FAHRENHEIT is a multiple of 10,and both numbers are integers, just how hot is it ??

Dharmpal Ji:

It depends where that hot summer day is. For most places, the anwwer is 95 (FAHRENHEIT). There could be places where the answer 140 (FAHRENHEIT) may work. I don't know if there is any place on globe where the temp. goes as high as 185 (FAHRENHEIT).

Budh ji well done you got 300%
3 right ans.
35C =95F will be ok most of the places.

is there a mathematical way to do this or is it just universal answer?

Yes, the equation 5(F-32) = 9C corelates FAHRENHEIT and CELSIUS. This is a single equation in two variables, F & C , thus there are infinitely many solutions. Just choose a value for one and calculate the other. Now there is another condition: F - C is a multiple of 10. Once you find one such pair (like 95 and 35), then all the remaining ones are
F = 95 + 45k where k is any integer. The number 45 comes in picture because it is smallest multiple of 9 & 5 which are used in corelation for F and C.

Budh Uncle ,

Very nice and simple explanation.
