Average calculation
Average calculationN = the number of terms
S = the sum of the numbers in the set.
Average = S/N
For example
The marks of a student in five subjects are 96, 94, 92, 87, and 81, then what is the average score of the student?
N = 5
S = 96 + 94 + 92 + 87 + 81 = 450
A = 450/5 = 90.
Another type questions
1). There are 36 boys and 44 girls in a class. The average score of boys is 40 and girls are 35. Then what will be the average mark?
Total mark of 36 boys = 36 x 40 = 1440
Total mark of 44 girls = 35 x 44 = 1540
Total mark of 80 Students = 1440 + 1540 = 2980
Average mark of the class = (2980 / 80)
= 37.25
2). The average weight of 15 members in a football team is 24 kg when a new member included, the average weight increases by 2. What is the weight of the new member?
Total weight of 15 member = 24 x 15 = 360
Average after including a new member = 24 + 2 = 26
Total weight of 16 member = 26 x 16 = 416
Weight of the new member = Total weight of 16 member - Total weight of 15 member
= 416 - 360
= 56.

Formula : .
Train Speed = Distance / Time.
Points to Remember .
To change km/hr into m/sec, we need to multiply it by 5 / 18. .
Example:.
90 km/hr means.
90 x 5 / 18.
= (5 x 5 ).
= 25 m/sec.
And if we need to convert m/sec into km/hr, we multiply it by 18 / 5.
Example:.
90 m/sec means.
90 x 18 / 5.
= ( 18 x 18 ).
= 324 km/hr.
