Two buses start from the same bus stand at 8 a.m. one travels at 40 km/h and other at 50 km/h. The second bus reaches the next stop at 10 a.m. How much later will the first bus arrive?

Answers:

Ans. Time taken by 2nd bus = 2 hours
speed of 2nd bus = 50km/h
total distance = speed × time
Total distance = 50 × 2 = 100 km

A rectangular tank is 48 cm long 35 cm wide and 40 cm height.It is 1/5 of its height.Water flows at the rate of 1.8 litre/minute.How much water is in the tank after 6 minutes.Give in litres.

Answers:

Given : Length of Tank = 48cm
Width of Tank = 35m
Height of Tank = 40 cm
1/5 of Height = 40*1/5 = 8cm
Volume of Tank = 48*35*8 = 13440 cm^{3}
We Know 1L = 1000 cm^{3}
Volume of Tank in Liter = 13.44L
A) If the water is flowing into the tank then,
rate of flow = 1.8L/m
total time = 6m
total volume = 1.8 * 6 = 10.8L
then Water in tank after 6 minuters = 13.44 + 10.8 = 24.24L
B) If the water is flowing out from the tank then,
Water in Tank after 6 minutes = 13.44  10.8 = 2.64L

United we stand speech for 1minute in a attractive manner

Answers:

United We Stand Divided We Fall
Unity is strength. A united group of people can always achieve more things than a single man. That is the reason groups are formed in many fields. In ancient times, man used to live alone. He traveled alone and hunted single handedly. But soon he realized that if he joins hands with his fellow men, he can face many of the common dangers. Thus villages were formed which in turn developed into towns, cities and countries. In modern times also groups are formed in all fields and walks of life. We have realized that by forming unions, we can demand and achieve things in a stronger way than by standing alone. There is the story of a rich old man who had tensions. But they always quarreled with one another. The old man knew that if he died, his wealth would be squandered by the quarrelling sons. So he called them to his side and showed a bundle of ten sticks. He asked each one of them to break it into two. But however they tried, none could break the bundle. Then he untied the bundle and gave them each a stick asking them to break it, which they did easily. Thus the sons realized their foolishness and began to live in harmony.
