An industrial loom weaves 0.128 metres of cloth every second. Approximately, how many seconds will it take for the loom to weave 25 metre of cloth ? Pick:
A) 194 seconds B) 195 seconds C) 196 seconds D) 197 seconds E) none of these

Rationale: "explanation : let the time required by x seconds . then , more cloth means more time ( direct proportion ) so , 0.128 : 1 : : 25 : x = > x = 25 ∗ 1 / 0.128 = > x = 195.31 so time will be approx 195 seconds option b"
Answer: B
