    1.A wood blog weights 30 kg. What will be the weight of the blog its thickness is   doubled and length is reduced to half. (3 marks)

    Answer.  60 Kg.

    Volume of blog = pi R2 L

    Thickness is doubled  and length is reduced by half

    So  R(final) = 2R

          L(final) =  L/2

    So the new volume will  be = pi(4R2)L/2

    i.e. = 2pi R2L

    so the volume will be doubled and also the weight will be

             __________                                             _______________

               C D E F                                                          BGA

    then find the value of X,Y,Z ,G

    Ans.

                         945                                                       945

                         +78                                                       -78

    4}A class has 50 students, 26 boys and 24 girls. The principal divided the students in group of 30 and 20.

    He doesn?t know the exact no. of boys or girls in the group. But the proportion of no. of boys in group A is more than that of the no. of  girls in group B.

    Then tell the difference in no. of boys in group A and girls in group B.

    Ans. 6.

     

    The proportion i.e. Ab:Ag> Bb: Bg  Thus Ab.Bg>Bb. Ag

    Now from hit and trial method we find that    Ab  Ag     Bb  Bg

                                                                            15    15      11   9         Ab. Bg                                                                                      16    14        10   10        Ab.Bg>Ag.Bb

    Thus Ab-Bg = 6

     

    5) given a two digit no. 15. write down a digit before it and after it so that the 4 digit no. so formed can be divisible by 15.how many such combination are possible.(3 marks)

    Ans 6.  1155, 4155, 7155, 3150, 6150, 9150

    For divisible by 15 in decimal place either there will be 0 or 5 and the sum of the 4 digit should be divisible by 3.

               

    6. A person has 4 enclosures of sheep. Each having different no. of sheeps. Once he counted the no. of sheep in all 4.
