Average Methods Example 1
In this average methods Example 1 we discuss some examples which help your better understanding in average chapter which came in most compititive exams.This is the basic theory of average which applied in question to obtain answers here is Average Methods of example 1 in different form of examples. This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam.Under below given some more example for your better practice.
Example 1:
There are two section X and Y of a College, consisting of 36 and 44 students respectively.if the average weight of section X is 40Kg and that of section Y is 35Kg . Find the average weight of the whole College (in Kg)?
Answer:
Step 1: At first the total ( X + Y ) college students are ( 36 + 44 ) = 80.
Step 2: college X total student weight and college Y total student weight is ( 36 x 40 + 44 x 35 ) = 2980
Average weight of the whole college is = 2980 / 80 = 37.25.
Example 2:
In a School 8 student average weight is increased by 3.5 kg when new student comes in place of one of them than weight become 55 kg.What might be the weight of the new student?
Answer :
Step 1: At first we find the total weight increased So, ( 8 X 3.5 )kg = 28kg.
Step 2: Now the weight of new Student is = ( 55 + 28 )kg = 83 kg.
So, the weight of the new student is 83 kg.
Example 3:
The Average weight 3 girls A, B, and C is 55kg,While the average weight of three boys B, D, and E is 57 kg. What is the average weight of A, B, C, D, E ?
Answer :
Step 1: At First we find 3 girls total weight ( A + B + C ) = ( 55 X 3 ) = 165 kg. and Total 3 boys weight of ( B + D + E ) = ( 57 x 3 ) = 171.
Step 2: Adding both weight of ( A + 2B + C + D + E ) = ( 165 + 171 ) = 336 kg.
Note: So, to find the average weight of A B C D and E, we duty to know B's weight, which is not given. So the data is inadequate.
