If the Arithmetic mean of 8, 6,4, x, 3, 6, 0 is 4; then the value of x = ……A) 7 B) 6 C) 1 D) 4

Answer»

Correct option is: C) 1

Given that mean of the data is 4.

\(\therefore\) \(\frac {8+6+4+x+3+6+0}7 = 4\)

\(\Rightarrow\) 27 + x = 7 \(\times\) 4 = 28

= x = 28-27 = 1

Hence, the value of x is 1.

Correct option is: C) 1
