Question

The mean of 1, 3, 4, 5, 7, 4 is m. The numbers 3, 2, 2, 4, 3, 3, p have mean m − 1 and median q. Then, p + q =
A. 4
B. 5
C. 6
D. 7

Answer 1

a-4

is the correct answer of this question

Answer 2

m = 4, p = 4, q = 4

Step-by-step explanation:

mean of 1, 3, 4, 5, 7, 4 is m.

N = 6

Sum = 24

So m = 24/6 = 4

Numbers 3, 2, 2, 4, 3, 3, p have mean m − 1 and median q

N = 7

Sum = 17 + p

Mean = m-1 = (17+p)/7

 7m - 7 = 17 + p

Substituting m = 4 here, we get:

 28 - 7 = 17 + p

 21 = 17 + p

p = 4

Median of the series = 7+1/2 = 4th item = 4

q = 4

p + q =  4 + 4 = 8

8 is not given in the options. So please recheck the question again.
