Figure shows three temperature scales with the freezing and boilling point of water indicated. A change of `25R^(@),25S^(0)` and `25U^(0)` is denoted by `x_(1),x_(2),x_(3)` respectively which of the following is correct:

Options

A. `x_(1)ge x_(2)ge x_(3)`
B. `x_(2)lex_(1)lex_(3)`
C. `x_(3)ge x_(2)ge x_(1)`
D. `x_(2)gex_(3)gex_(1)`

Answer

D

Explanation

`1^(@)R = 1^(@)C`
`1^(@)S=100/70=10/7 ^(@)C`
`1^(@)U = 100/75=4/3^(@)C`
`1^(@)Sge 1^(@)Uge 1^(@)R`
`Rightarrow x_(2)ge x_(3) ge x_(1)`
