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 ? | [
"194 seconds",
"197 seconds",
"None of these",
"195 seconds"
] | D | 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

The length of a train and that of a platform are equal. If with a speed of 90 k/hr, the train crosses the platform in one minute, then the length of the train (in meters) is: | [
"896",
"258",
"750",
"693"
] | C | Explanation:
Speed = [90 * 5/18] m/sec = 25 m/sec; Time = 1 min. = 60 sec.
Let the length of the train and that of the platform be x meters.
Then, 2x/60 = 25 è x = 25 * 60 / 2 = 750
