Question

On an X temperature scale, water freezes at `-125.0^(@) X` and boils at `375.0^(@) X`. On a Y temperature scale, water freezes at `-70.0^(@)Y` and boils at `-30.0^(@)Y`. The value of temperature on X-scale equal to the temperature of `50.0^(@)Y` on Y-scale is
A. `455.0^(@) X`
B. `-125.0^(@) X`
C. `1375.0^(@) X`
D. `1500.0^(@) X`

Answer 1

Correct Answer - C
`(X-(-125))/(500) = (Y-(-70))/(40)`
For `Y=50`
`X = 1375.0^(@)X`.
