Q: 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?

Let the required time be x seconds. More metres, More time (Direct Proportion) ∴ 0.128 : 25 :: 1 : x ⟺ 0.128x = 25 x 1 x = 25 = 25 x 1000 0.128 128 ⟹ x = 195.31. ∴ Required time = 195 sec (approximately).

178
195

Correct Answer: 195

Explanation:

Let the required time be x seconds.

More metres, More time (Direct Proportion)

∴ 0.128 : 25 :: 1 : x ⟺ 0.128x = 25 x 1

x =	25	=	25 x 1000
	0.128		128

⟹ x = 195.31.

∴ Required time = 195 sec (approximately).
