Multiple Choice Questions - Set - 3
Question 1:
The median from the table is
Value | Frequency |
7 | 2 |
8 | 1 |
9 | 4 |
10 | 5 |
11 | 6 |
12 | 1 |
13 | 3 |
(a) 11
(b) 10
(c) 12
(d) 11.5
Correct Answer – (B)
Question 2 :
If mean = (3 median – mode) . k, then the value of k is
(a) 1
(b) 2
(C) 1/2
(d) 3/2
Correct Answer – (C)
⇒ 2 mean = 3 median – mode
⇒ mean = 12 (3 median – mode)
⇒ k= 12
Question 3 :
Mode is the value of the variable which has:
(a) maximum frequency
(b) minimum frequency
(c) mean frequency
(d) middle most frequency
Correct Answer – (A)
Question 4 :
For the following distribution:
Marks | Number of Students |
Below 10 | 3 |
Below 20 | 12 |
Below 30 | 27 |
Below 40 | 57 |
Below 50 | 75 |
Below 60 | 80 |
the modal class is
(a) 10 – 20
(b) 20 – 30
(c) 30 – 40
(d) 50 – 60
Correct Answer – (C)
Question 5 :
Mean of n numbers x1, x2, … xn is m. If xn is replaced by x, then new mean is
(a) m – xn + x
(b) (nm – xn + x)/n
(c) [(n – 1)m + x]/n
(d) (m – xn + x)/n
Correct Answer – (B)
Question 6 :
The median of set of 9 distinct observations is 20.5. If each of the largest 4 observations of the set is increased by 2, then the median of the new set
(a) is increased by 2
(b) is decreased by 2
(c) is two times of the original number
(d) Remains the same as that of the original set.
Correct Answer – (D)
∴ median = 5th observation
∵ The largest four observations are increased
∴ 5th observation remains unchanged.
Question 7 :
Mode and mean of a data are 12k and 15A. Median of the data is
(a) 12k
(b) 14k
(c) 15k
(d) 16k
Correct Answer – (B)
⇒ 12k = 3 median – 2 × 15k
⇒ 42k = 3 median
⇒ Median = 14k.
Question 8 :

Class | Frequency |
13.8 – 14.0 | 2 |
14.0 – 14.2 | 4 |
14.2 – 14.4 | 5 |
14.4 – 14.6 | 71 |
14.6 – 14.8 | 48 |
14.8 – 15.0 | 20 |
The number of atheletes who completed the race in less then 14.6 seconds is: [NCERT Exemplar Problems]
