If the coefficient of variation and standard deviation are ( 60 ) and ( 21 ) respectively, the arithmetic mean of distribution is

Options

  1. A( 30 )
  2. B( 21 )
  3. C( 60 )
  4. D( 35 )

Correct answer

D. ( 35 )

Step-by-step solution

We know that, coefficient of variation (= 100 % ) ( 60= 21 100 ), substitute the given values ( = 2100 60 =35 )
