Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

The mean of eight numbers is 42. If one number is 63, then the mean of the remaining numbers is :

• 36

• 37

• 38

• 39

EVALUATION

Here it is given that the mean of eight numbers is 42

Sum of eight numbers

= 8 × 42

= 336

Now one number is 63

Number of remaining numbers

= 8 - 1

= 7

Sum of the remaining 7 numbers

= 336 - 63

= 273

Hence the required mean

$\displaystyle \sf{ = \frac{273}{7} }$

$\displaystyle \bf{ = 39 }$

FINAL ANSWER

Hence the correct option is 39
