Step-by-step explanation:

As median of the 10 number is 24.

So,1/2(5th number+6th number)=24

x+1+2x−13

=24

3x−12

=24

3x=60

x=20

So, 5th number=x+1=21

6th number=2x-13=27

So, mean=

6+14+15+17+21+27+30+32+34+43

=23.9

Answer (B) 23.9

Answer :D

3, 8, 14, x + 6, 2x - 3, 25, 32, 50

Number of observations = 8 (even)

Median = [(n/2)th observation + {(n/2) + 1} th observation] ÷ 2 "where n represents number of observations"

18 = [(4th observation) + (5th observation)] ÷ 2

18 = [(x + 6) + (2x - 3)] ÷ 2

18 × 2 = [x + 6 + 2x - 3]

36 = 3x + 3

36 - 3 = 3x

33 = 3x

x = 11
