Correct option is C
Given:
Median = 350
Total frequency = 40
Sum of frequencies: 4 + 6 + x + 10 + y + 8 = 40
Formula Used:
Median =
Solution:
From the sum of frequencies:
28 + x + y = 40
x + y = 12
Since the median is 350, the median class is 300-400.
Lower limit L = 300
Class width h = 100
Frequency of median class f = 10
Cumulative frequency of class preceding median class cf = 4 + 6 + x = 10 + x
Total frequency N = 40, so = 20
Applying the median formula:
350 =
50 =
50 = (10 - x) × 10
5 = 10 - x
x = 5
Substitute x = 5 into the equation x + y = 12:
5 + y = 12
y = 7
Final Answer
So the correct answer is (c)
