    sir in question 9 ( 18:44 ) if we say : 4 log 13- 3( log 11 + log 13 ) + log 11 + log 100 - log 13 - log 100 + 2 log 11 the answer comes as Zero. kindly solve the confusion

    In Q5. The first part can we solve more easily just by applying property as log base 10 to power one is zero... So simply _(a+1) ... Taking minus as Common

    In a class with a certain number of students, if one student weighing 50 kg is added then the average weight of the class increases by 1 kg. If one more student weighing 50 kg is added, then the average weight of the class increases by 1.5 kg over the original average. What is the original average weight (in kg) of the class?

      Avg = sum / n
      Let , original average = x
      Original no of students = n
      Then sum = xn
      X = sum/n
      After adding 1 50kg student
      X+1 = xn +50 / n+1. .......(1) eq
      After another students
      Original average increase by 1.5 kg
      X + 1.5 = xn +50+50/ n+2 .....(2) eq
      After solving these you get the value of X = 47 and N =2
