An industrial loom weaves 0.128 metres of cloth every second. Approximately, how many seconds will it take for the loom to weave 25 metres of cloth?
178
195
204
488
Explanation:
Le the required time be $ x $ seconds.
More metres, More time (Direct Proportion)
$\therefore$ 0.128 : 25 :: 1 : $ x $ $\Leftrightarrow$ 0.128$ x $ = 25 x 1
| $ x $ =$ \dfrac{25}{0.128} $=$ \dfrac{25 \times 1000}{128} $ |
$\Rightarrow x $ = 195.31.
$\therefore$ Required time = 195 sec (approximately).
