Question: What is the mean of the range, mode and median of the data given below?
5, 10, 3, 6, 4, 8, 9, 3, 15, 2, 9, 4, 19, 11, 4
Solution:
Given data = 5, 10, 3, 6, 4, 8, 9, 3, 15, 2, 9, 4, 19, 11, 4
Arranging in ascending order = 2, 3, 3, 4, 4, 4, 5, 6, 8, 9, 9, 10, 11, 15, 19
Here,
Most frequent data is 4
So, Mode = 4
Total terms in the given data, (n) = 15 (It is odd)
∴ Median = {(n + 1)/2}th term
= {(15 + 1)/2}th term
= (8)th term
= 6
Now,
Range = (Maximum value - Minimum value) + 1
= (19 - 2) + 1
= 18
∴ Mean of Range, Mode and Median = (Range + Mode + Median)/3
= (18 + 4 + 6)/3 = 28/3 = 9.33

প্রশ্ন: যদি U = {1, 2, 3, 4, 5, 6, 7} এবং P = {2, 3, 5} এবং Q = {4, 6} হয়, তবে P ∩ Q' = কত?
সমাধান:
দেওয়া আছে, U = {1, 2, 3, 4, 5, 6, 7}
P = {2, 3, 5} এবং Q = {4, 6}
এখন, Q' = U - Q = {1, 2, 3, 4, 5, 6, 7} - {4, 6}
= {1, 2, 3, 5, 7}
P ∩ Q' = {2, 3, 5} ∩ {1, 2, 3, 5, 7} = {2, 3, 5} = P
∴ P ∩ Q' = P

Question: What is the 9th term of the sequence : - 2, - 4, - 6, ............................ , - 100?
Solution:
Here,
- 4 - (- 2) = - 4 + 2 = - 2
- 6 - (- 4) = - 6 + 4 = - 2
∴ d = - 2
a = - 2
n = 9
∴ The 9th term of the sequence = a + (n - 1)d
= - 2 + (9 - 1) (- 2)
= - 2 + 8 (- 2)
= - 2 - 16
= - 18

প্রশ্ন: যদি 8Pr = 336 হয়, তাহলে r এর মান কত?
সমাধান:
8Pr = 336
⇒ 8!/(8 - r)! = 336
⇒ 40320/(8 - r)! = 336
⇒ (8 - r)! = 40320/336
⇒ (8 - r)! = 120
⇒ (8 - r)! = 5!
⇒ 8 - r = 5
⇒ r = 8 - 5
∴ r = 3
