Average Methods Example 2
The result obtained by adding several quantities together and then dividing this total by the number of quantities is called Average.This is the basic theory of Speed Time and Distance which is applied in question to obtain answers here is Speed Time and Distance Methods of example 2 in different form of examples.
In maths exam papers there are two or three question are given from this chapter.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:
The average age of 34 students in a school is 15 years, after that when geography teacher's age is added to student age then the average age increases by one, Find what is the teacher's age in years ?
Answer :
Step 1:T first we find the total student ages with out adding teacher's age that is ( 34 x 15 ) = 510 years.
Now we find out the age of students adding with teachers age that is ( 35 x 16 ) = 560 years.
Step 2: Teachers age is ( 560 - 510 ) = 50 years.
Example 2:
The average age of 45 students in a batch is 18 years. The average age of 23 students is 16 years. Find average age of remaining 16 students ?
Answer :
Step 1: At first we find the age total age of 45 and 23students is (45 x 18 ) = 810 and ( 23 x 16 ) = 368.
Step 2: Sum of the ages of 16 students is = ( 810 - 368 ) = 442.
So average age of is ( 442 / 16 ) = 28 years.
Example 3:
The weight of 5 tanks of 57Kgs, 42Kgs, 45Kgs, 63Kgs,74Kgs.Find its average?
Answer:
Average = 58 + 42 + 45 + 63 + 74 / 5
= 282 / 5 = 56.4
