Question

The average of four number is 32.three of the numbes are 26 ,40,34 . Find the fourth number ?

Answer 1

Answer:

Average= Sum/Total Number

Let the 4th no. be x.

= 26+40+34+x/4= 32

= 100+x/4=32

Then multiply 32 and 4= 32×4= 128

= 128-100

= 28

∴ the fourth no. is 28.

Answer 2

The given question is The average of four numbers is 32. three of the numbers are 26, and 40,34. Find the fourth number.

The average of the four numbers is 32

Out of four, their numbers were given 34,26,40.

we have to find the fourth number.

let the unknown number be x.

The average is calculated by dividing the sum of the digits by the number of digits.

Here the sum of the digits is

$26 + 40 + 34 + x = 100 + x$

The expression of the average will be

$\frac{100 + x}{4} = 32$

we have to find the value of x in the above expression.

The 4 dividing On the left side multiplies the number on the right side.

$100 + y = 4(32) \\ 100 + y = 128$

Then 100 adding on the left will gets subtracted on the right.

$y = 125 - 100 = 28$

Therefore, the value obtained is 28.

hence, the final answer to the given question is 28.
