A faulty thermometer reads 5^@C and 99^@Cin ice and steam, respectivel

1.	A faulty thermometer reads 5^@C and 99^@Cin ice and steam, respectively. If this thermometer reads 62^@C , find the correct temperature in ""^@C .
Answer» Solution :`(T_C - 0)/(100 - 0) = ("Temperature of faulty SCALE - LOWER fixed point")/("Upper fixed point - Lower fixed point")` ` rArr (T_C - 0)/(100) = (62 - 5)/(99 - 5) = 57/94` ` rArr T_C=(57 xx 100)/(94)= 60.64^@C`
