In a class there are 13 students in house A, 10 in house B, 12 in house C and 10 in house D. What percentage of students are there in house C?

Posted by Rohini Yadav (Feb 15, 2017 7:40 p.m.) (Question ID: 2157)

  • Answers:
  • Total students = 13 + 10 + 12 + 10 = 45

    Percent of students in house C = (Part / Whole) x 100

    = (No. of students/Total Students) × 100

    = (12/45) × 100

    = 26.67%

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?

Posted by Rohini Yadav (Feb 05, 2017 7:06 p.m.) (Question ID: 1841)

  • 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

    speed of first bus = 40km/h

    Time taken to reach  = distance/speed

    => 100/40 = 5/2 h = 2 hours 30 minutes

    So first bus 'll reach at 10:30 am

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.

Posted by Monika Raghuwanshi (Jan 13, 2017 5:47 p.m.) (Question ID: 1343)

  • 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 cm3

    We Know 1L = 1000 cm3

    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

  • Answers:
  • Take HCF of numerator and denominator. Then divide both numerator and denominator by HCF. You will get simplest form of a fraction.

    Ex.    85/119

    HCF of 85 and 119 is 17.

    Now,       (85/17)/(119/17)

    = 5/7

  • 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.

Posted by sadaf mujawar (Nov 08, 2016 3:45 p.m.) (Question ID: 496)

  • Area of bigger envelope is 50cm * 80 cm= 4000cm^2

    So number of envelopes= Area of bigger envelope/ area of small envelope
