Question

State 'T' for true and 'F' for false.
(I) $12$ hours $:30$ hours $=8$km $:20$km
(II) The ratio of $1$ hour to one day is $1:1$
(III) The two terms of a ratio can be in two different units.

• A. (I)-T, (II)-T, (III)-T
• B. (I)-F, (II)-F, (III)-F
• C. (I)-T, (II)-F, (III)-F
• D. (I)-F, (II)-T, (III)-F

Answer 1

The correct option is C (I)-T, (II)-F, (III)-F

$i)$ $12$ hours $:$ $30$ hours$=8Km:20Km$

$\frac{12}{30}=\frac{2}{5}$ hours.

$\frac{8}{20}=\frac{2}{5}$ Km.

Hence, $True.$

$ii)$ The ratio of $1$ hour to $1$ day,

$\frac{1hour}{1day}=\frac{1}{24}hours\ne 1$

Hence, $false.$

$iii)$ The two terms of a ratio can not be in two different units.

Hence, $false$.
$\left(I\right)-T,\left(II\right)-F,\left(III\right)-F$
