7382 . A man walking at the rate of 5 km/hr crosses a bridge in 15 minutes. The length of the bridge (in meters) is-

A. 600
B. 750
C. 1000
D. 1250

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

Rate for walking per minute = (5×1000)/60 meter = 250/3 meter

In 1 minute he crosses 250/3 meter

In 15 minute he crosses 250/3 meter

15 minute he crosses = (250×15)/3 = 1250 meter

So, the length of the bridge is 1250 meter.

A. 60 kmph
B. 55 kmph
C. 63 kmph
D. 57 kmph

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

To calculate the speed of the train, we can use the information that the man can count 21 telephone posts in one minute and that the posts are known to be 50 meters apart. This means that in one minute, the train travels a distance equal to the spacing between 21 telephone posts.

Distance traveled in one minute = 21 posts * 50 meters/post = 1050 meters

Since there are 60 seconds in a minute, we need to convert the distance to meters per second:

Speed (in meters per second) = Distance (in meters) / Time (in seconds) Speed = 1050 meters / 60 seconds = 17.5 meters/second

To express the speed in kilometers per hour (km/h), we can multiply by 3.6 (since 1 meter per second is equal to 3.6 kilometers per hour):

Speed = 17.5 meters/second * 3.6 km/h = 63 km/h

So, the speed of the train is 63 kilometers per hour.

Explanation:

40 ঘন্টার জন্য regular pay ( 30 × 40) টাকা = 1200 টাকা।

Overtime এর টাকার পরিমান ( 1680 - 1200) টাকা = 480 টাকা

যেহেতু, Overtime এর প্রতিদিনের টাকার পরিমান Regular Payment এর দ্বিগুন , সেহেতু overtime এর সময় ( 480 ÷ ( 30 × 2) ) ঘন্টা = 8 ঘন্টা
