Question

The average mark in 2 subjects is 35 and in three other subject is 40 . Then find the average mark in all the five matches?

Answer 1

average mark in two subjects=35
sum of mark=70
average mark in 3subjects=40
sum=120
total average=(120+70)/2=190/2=95

Answer 2

Answer:

38

Step-by-step explanation:

The average mark in 2 subjects is 35

$Average = \frac{\text{Sum of scores of both subjects }}{2}$

$35 = \frac{\text{Sum of scores of both subjects}}{2}$

$70= \text{Sum of scores of both subjects}$

The average in three other subject is 40

$Average = \frac{\text{Sum of scores of both subjects }}{2}$

$40 = \frac{\text{Sum of scores of other three subjects}}{3}$

$120= \text{Sum of scores of other three subjects}$

$\text{Average of all five subjects} = \frac{\text{Sum of scores of 5 subjects }}{5}$

$\text{Average of all five subjects} = \frac{70+120}{5}$

$\text{Average of all five subjects} =38$

Hence the average mark in all the five matches is 38
