A thermometer has its lower fixed point ...

A thermometer has its lower fixed point and upper fixed point marked as 0.5 and 101 respectively. What is the reading on this thermometer at `30^@`C.

Text Solution

Verified by Experts

Let the reading be t degree,
`therefore " " (t-0.5)/(101-0.5)=C/100 " or ", (t-0.5)/(100.5)=30/100`
or, `" " 10t-5=301.5 " or, " t=30.65` degree
Hence, the faulty thermometer reads 30.65 degree.
