the mean of marks scored by 100 students was found to be 40. Later on, it was discovered that a score of 53 was misread as 83. F
liberstina [14]

As the sum of marks of others remain unchanged , let their sum be x . As the mean using 83 was 40 , we have ,

x = 3917

Now mean using 53 ,

What is the solution to the system of equations <br><br> 3x+2y=39<br> 5x-y=13
Marta_Voda [28]

3x + 2y = 39

5x - y = 13

Multiplying the last by two:

10x - 2y = 26

Adding to the first

13x = 65

x = 5

y = 5x-13 =25-13=12


Check:

3(5)+2(12)=39 good

5(5)-12=13 good


Answer: x=5, y=12
