Average Methods Example 3

We can say that **average is an sum of n number and divided by n**.

We elaborate this a student score in 35, 56, 65 in three different subjects respectively, than the average score in subject is 35 + 56 + 65 / 3 = 52. So here is some average methods and shortcut tricks example 3 we discuss. 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

Example #2

The average marks acquired by 140 students in a final examination is 32. If the average marks of failed students are 18 and the average marks of passed students are 38. What is the passed students in examination.

- 98
- 88
- 92
- 94

**Answer:**Option (A)

**How to Solve**

Number of passed students are = Total students ( Total average – Failed average ) / Passed average – Failed average

= 140 ( 32 – 18 ) / ( 38 – 18 )

= 1960 / 20 = 98

Example #3

A city center has an average of 610 visitors on sunday and 340 on other days. The average number of visitors per day in a month of 30 days beginning with a Sunday is.

- 355
- 385
- 395
- 400

**Answer:**Option (B)

**How to Solve**

Since the month begins with a Sunday, So there will be five Sundays in the month

= ( 610 x 5 + 340 x 25 ) / 30

= 3050 + 8500 / 30

= 11550 / 30 = 385.

Example #4

The average of 6 numbers is X and average of 3 of these is Y. If the average of the remaining 3 is Z, then

- 2x = 2y + 2z
- x = 2y + 2z
- x = y + z
- 2x = y + z

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (D)

**How to Solve**

Here we have x is average of three of these is y so, 3y and average of the remaining three is z so,

x = 3y + 3z / 6

x= 3 ( y + z ) / 6

x = ( y + z ) / 2

2x = y + z.

Example #5

The average marks of first 54 group members is 62 and second 62 group members is 65 and third 48 group members is 70 respectively. Then, what would be the average marks of all the students?

- 55.95
- 55.47
- 65.47
- 62.47

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (C)

**How to Solve**

**Step 1:**At First we find the total students marks according with 3 group

= ( 54 x 62 ) + ( 62 x 65 ) + ( 48 x 70 ) = ( 3348 + 4030 + 3360 ) = 10738.

**Step 2:**Now we need to find average marks of all three groups.

Total groups members are = ( 54 + 62 + 48 ) = 164.

Average marks of all the students = 10738 / 164 = 65.47.
