Question

1,2,3,4,5,6,7,y,9,9,10,12,14,16 meaidan is 8 find y

Answer 1

Total numbers are 14 (even)

so to get median we have to find mean of 7th and 8th term

◆since they are arranged in ascending order so no need to arrange.◆

$median = \frac{7 + y}{2} \\ 8 = \frac{7 + y}{2} \\ 16 = 7 + y \\ y = 9$
value of y is 9

Answer 2

[{(4+2)³ x3³} -7²]² / (5²-3²)²
