Question

the average of 3 no is 16.one of these no is 14. what is tha average of tha remaining 2 no is?​

Answer 1

Given average of 3 numbers is 16

Given average of 3 numbers is 16Let the 3 numbers be x , y, z

then x+y+z / 3 = 16

x = 14

then 14 + y + z / 3 = 16

14 + y + z = 48

y + z = 34

average = y + Z / 2 = 34/2 = 17

Hence the average of remaining 2 numbers is 17

Answer 2

1) Let the two numbers be x, y

Known number = 14

Average of three numbers = 16

Sum of observations/Number of numbers = 16

(14 + x + y)/3 = 16

14 + x + y = 16 * 3

14 + x + y = 48

x + y = 48 - 14

x + y = 34

2) Sum of other two numbers = x + y = 34

Number of observations = 2

Average of other two number = Sum of other two numbers/Number of observations

= 34/2

= 17

Average of other two numbers = 17
