Moderate

A

$60^{0} C$
B

$50^{0} C$
C

$30^{0} C$
D

$10^{0} C$

Solution

$r e l a t i o n b e t w e e n c e n t i g r a d e t h e r m o m e t e r a n d f a u l t y t h e r m o m e t e r i s \frac{C}{100} = \frac{X - L F P}{U F P - L F P} h e r e L F P i s l o w e r f i x e d p o i n t = 5; U F P i s u p p e r f i x e d p o i n t = 95; X i s r e a d i n g o n f a u l t y t h e r m o m e t e r = 59 s u b s t i t u t e g i v e n v a l u e s i n a b o v e e q u a t i o n \frac{C}{100} = \frac{59 - 5}{95 - 5} \Rightarrow \frac{C}{100} = \frac{54}{90} \Rightarrow C = 60^{0} C$
