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 ?

1178
2195
324
4488

Answer:- 1

Explanation:-

Solution:

Let the required time be x seconds
Then,
More metres, More time (direct proportion)

\begin{aligned} ∴ 0.128 : 25 :: 1 : x \\ \Leftrightarrow x = \frac{25}{0.128} \\ \Leftrightarrow x = \frac{25 \times 1000}{128} \\ \Leftrightarrow x = 195.31 \end{aligned}

$\eqalign{ & \therefore 0.128:25::1:x \cr & \Leftrightarrow x = \frac{{25}}{{0.128}} \cr & \Leftrightarrow x = \frac{{25 \times 1000}}{{128}} \cr & \Leftrightarrow x = 195.31 \cr}$ `
∴ Required time =195 seconds (approx)
