HELLO DEAR,

MEDIAN IS 525
500 - 600 is median class

we know median = $\bold{ l + \frac{\frac{n}{2} - cf}{f} * h}$

where, l = lower limit of median class = 500
h = class interval = 100 - 0 = 100
∑f_i = n = 100
cf = cumulative frequency before class median = 36 + x
f = median frequency

525 = $\bold{ 500 + \frac{\frac{100}{2} - (36 + x)}{20} * 100}$

⇒525 = 500 + {50 - (36 + x)} * 5

⇒525 - 500 = {50 - (36 + x)}*5

⇒25/5 = 50 - (36 + x)

⇒36 + x = 50 - 5

⇒x = 45 - 36

⇒x = 9

and
∑f_i = 76 + x + y

100 = 76 + x + y

9 + y + 76 = 100

y = 100 - 85

y = 15

I HOPE ITS HELP YOU DEAR,
THANKS
